Murata Launches World’s First 10µF/50Vdc MLCC in 0805-inch Size for Automotive Applications
  Murata Manufacturing Co., Ltd. has announced the new GCM21BE71H106KE02 multilayer ceramic capacitor (MLCC) has entered mass production. The device is the world's first 0805-inch size (2.0 x 1.25 mm) MLCC to offer a capacitance of 10µF with a 50Vdc rating and is specifically engineered for automotive applications*. This cutting-edge product marks a significant advancement in MLCC design, delivering a smaller 0805-inch package while maintaining capacitance, voltage rating, and MLCC reliability.  Advancements in advanced driver-assistance systems (ADAS) and autonomous driving (AD) technologies necessitate deploying an increased number of integrated circuits (ICs) within vehicle systems. This surge in ICs simultaneously leads to a greater demand for supporting high-capacitance passive components while imposing tighter spatial constraints – as a greater number of capacitors must be accommodated on increasingly crowded automotive printed circuit boards (PCBs).  Designed for 12V automotive power lines, the GCM21BE71H106KE02 capacitor leverages Murata’s proprietary ceramic material and thinning technologies to help engineers to save PCB space and reduce the overall capacitor count, resulting in smaller, more efficient, and reliable automotive systems. As the first automotive-specific MLCC to achieve a 10µF capacitance with a 50Vdc rating in the compact 0805-inch size the GCM21BE71H106KE02 represents a significant advancement in capacitance efficiency. It offers roughly 2.1 times the capacitance of Murata’s previous 4.7µF/50Vdc product, despite sharing the same physical size. Furthermore, compared to the previous 10µF/50Vdc MLCC in the larger 1206-inch size (3.2 x 1.6 mm), the new MLCC occupies approximately 53% less space, providing substantial space savings for automotive applications.  Murata will continue to pursue further miniaturization and increased capacitance of MLCCs, while expanding its product lineup to meet the evolving needs of the automotive market. These efforts will support the industry as they look to develop higher-performance and more multifunctional vehicles. In addition, by downsizing electronic components, Murata aims to reduce material usage and improve production efficiency per unit, helping to lower electricity consumption at its manufacturing sites and reduce overall environmental impact.

Murata Unveils High-Efficiency 1W DC-DC Converter with Reinforced Isolation and Ultra- low Capacitance
  Murata Manufacturing has launched the NXJ1T series, a high-performance 1W DC-DC converter designed to provide reinforced isolation for communication interfaces and analog front-end (AFE) measurement circuits. With 4.2kVDC isolation (Hi Pot Test) and compliance with UL62368 safety standards, the NXJ1T series delivers exceptional electrical isolation, noise immunity, and thermal reliability for industrial, energy, and medical applications.  As industries transition to higher voltage systems, particularly in 800V electric vehicles (EV) and supporting chargers, battery energy storage (BESS), and renewable energy infrastructure, the need for robust isolation in communication and sensing systems has become increasingly critical. Furthermore, in medical applications, where low leakage current and safety isolation are essential, reliable power solutions must also meet stringent regulatory requirements like ANSI/AAMI ES60601-1.  Murata’s NXJ1T series addresses these challenges, offering a compact (10.55mm x 13.70mm x 4.04mm), high-performance DC-DC converter engineered for safety and durability in the most demanding environments. It features an unregulated 1W 5V input to 5V/200mA output design, ideal for embedded systems. Murata's proprietary molding technology provides the NXJ1T series with high ingress protection against dust and particulates in harsh industrial environments and extreme temperatures. During development, the DC-DC converter has successfully undergone 1,000 temperature cycles between -40°C and 125°C, demonstrating its ability to withstand the highest levels of thermal stress.  Manufactured in the UK, the NXJ1T incorporates Murata’s proprietary block-coil transformer technology, providing high isolation, low leakage current, and exceptional performance. In contrast to many alternative solutions on the market, which utilize wireless power coils that exhibit low coupling factors, high switching frequencies (approximately 10 MHz), and low efficiencies of typically around 40-60%, Murata's block-coil transformer technology facilitates lower switching frequencies (500 kHz–2 MHz) and higher efficiencies of approximately 80%. The result is exceptional common mode transient immunity (CMTI) and significantly lower isolation capacitance, making the NXJ1T series an ideal choice for engineers requiring high-performance power isolation in electrically noisy environments.  Each device features UL62368 recognition including reinforced insulation to 200Vrms and basic insulation to 250Vrms, providing an added layer of protection in high-voltage environments, while the under-voltage lockout (UVLO) functionality enhances operational stability, preventing erratic behavior under fluctuating power conditions. Furthermore, in medical equipment, where low leakage current is critical for patient-connected applications, the NXJ1T’s ultra-low isolation capacitance helps minimize unwanted leakage, supporting compliance with stringent safety standards like IEC 60601-1 when used within a certified system.  With a standard industry pin out and compact surface mount device (SMD) package, the NXJ1T provides seamless system integration into applications such as CAN Bus systems in EV chargers, heavy industrial automation systems, and medical instrumentation including X-ray, laser, ultrasound, and surgical instrumentation. In these high-voltage deployments, the DC-DC converters can deliver long-term stability and safety in high-voltage applications.  “As power system voltages continue to rise across industrial, and medical sectors, engineers require robust isolation solutions that can withstand demanding environments while maintaining efficiency,” said Ann-Marie Bayliss, Product Manager at Murata. She continued, “With its advanced transformer technology, the NXJ1T series delivers class-leading isolation, ultra-low leakage current, and high reliability, helping designers create safer and more efficient systems across a wide range of applications.”

Commercialized high precision agricultural CO2 sensors with superior long-term stability
  Murata Manufacturing Co., Ltd. (hereinafter "Murata") has commercialized "IMG-CA0012-12" (hereinafter "this product"), a case and cable type CO2 sensor. This high precision product primarily connects to environment measurement equipment in agricultural greenhouses and stably measures CO2 concentration. Through linkage with photosynthesis accelerators, this product will contribute to improving crop quality and increasing yield. Additionally, it improves energy efficiency by injecting an optimal amount of CO2 at an optimal timing. Mass production and supply for this product has begun in Hakui Murata Manufacturing.  In the field of agriculture, increased yield and quality improvement per unit area are required since there is a reduction in yield and decline in quality due to global warming as well as a drop in agricultural worker population. Technology for accelerating crop photosynthesis using CO2 application is an effective means of addressing these challenges. Furthermore, due to the recent increase in energy costs, effective CO2 application based on environmental data measurements is crucial. As a result, high-precision CO2 sensors, which offer long-term stability, require no calibration, and are resistant to malfunction, play a crucial role in photosynthesis accelerator technology.  This product is equipped with an automatic calibration function that runs on our unique calibration curve algorithm and dual wavelength (for measurement and reference) NDIR*1. Therefore, atmospheric calibration is not required. This ensures high precision and long-term stability, making it maintenance-free. Furthermore, its case and cable type design enhances user handling and ease of installation.  *1NDIR: Non-Dispersive Infrared Absorption  Specifications  CO2 sensors were installed in greenhouses and were used for a year for tomato cultivation and 2 years for rose cultivation. After use, CO2 concentration characteristics and temperature characteristics were evaluated.  It was discovered that CO2 concentration differences were minimal even when they were used for a long period of time in actual fields.  CO2 concentration characteristics  Temperature characteristics
