Murata Manufacturing Co., Ltd. has achieved a groundbreaking milestone in automotive electronics with the introduction of the GCJ21BD72A225KE02, an innovative soft-termination chip MLCC designed specifically for automotive powertrain and safety equipment. This revolutionary component represents the world’s first soft-termination chip MLCC to achieve 2.2μF capacitance at 100Vdc within the compact 0805-inch (2.0×1.25mm) form factor, setting a new benchmark for the automotive industry.
Addressing Critical Automotive Electronics Challenges
The automotive industry is experiencing unprecedented transformation as vehicle electrification accelerates and autonomous driving (AD) alongside advanced driver-assistance systems (ADAS) become increasingly sophisticated. Engineers today face mounting pressure to integrate more functionality into progressively smaller board spaces while maintaining uncompromising reliability standards.
The expanding adoption of 48V power systems across modern vehicles has created urgent demand for components that successfully combine high capacitance, exceptional voltage tolerance, and minimal footprint. Simultaneously, mechanical stress resulting from board flexure—caused by vibration and thermal cycling during vehicle operation—remains a persistent reliability concern for automotive manufacturers. The GCJ21BD72A225KE02 soft-termination chip MLCC comprehensively addresses all these critical challenges.
Revolutionary Miniaturization Achievement
Built upon Murata’s proprietary ceramic material design, incorporating advanced fine particle size and uniformity control technologies, this soft-termination chip MLCC achieves what was previously impossible. The 2.2μF capacitance at 100Vdc rating in the 0805-inch size represents capability that was formerly only achievable in the significantly larger 1206-inch (3.2×1.6mm) package.
This technological breakthrough delivers approximately 51% reduction in board mounting area compared to Murata’s previous 2.2μF/100Vdc offering. Additionally, it provides approximately 2.2 times increase in capacitance over the company’s previous 0805-inch, 100Vdc product. These improvements enable automotive designers to create more compact, efficient electronic systems without sacrificing performance or reliability.
Enhanced Reliability Through Soft Termination Technology
The soft termination feature incorporated into this soft-termination chip MLCC significantly enhances field reliability by effectively absorbing board flexure stress and reducing post-mounting cracking. This is particularly crucial in automotive applications where components must withstand harsh operating conditions including extreme temperature variations, constant vibration, and mechanical shocks throughout the vehicle’s operational lifetime.
The GCJ21BD72A225KE02 supports an extensive operating temperature range of -55°C to +125°C and meets X7T temperature characteristics per EIA standards, ensuring consistent performance across diverse automotive environments from freezing winter conditions to intense under-hood heat.
Applications in Modern Automotive Systems
This advanced soft-termination chip MLCC is ideally suited for critical automotive applications including:
- Powertrain Control Systems: Engine control units (ECUs), transmission controllers, and electric motor drives
- Safety Equipment: Airbag systems, electronic stability control, and collision avoidance systems
- ADAS Components: Radar systems, camera modules, and sensor fusion units
- 48V Power Systems: DC-DC converters, battery management systems, and power distribution units
- Autonomous Driving Electronics: High-performance computing platforms and communication modules
Meeting Future Automotive Demands
As vehicles evolve toward full electrification and autonomy, the demand for high-performance, reliable, and compact electronic components will only intensify. The GCJ21BD72A225KE02 soft-termination chip MLCC positions automotive manufacturers to meet these emerging challenges while maintaining the highest standards of safety and reliability.
Murata remains committed to expanding its automotive-grade MLCC lineup, continuously delivering the miniaturization, high capacitance, high voltage ratings, and exceptional reliability that next-generation vehicles demand.
