The Murata 2.2μF 100Vdc MLCC has officially been introduced to the market, marking a massive technological milestone for automotive electronics. Specifically designated as the GCJ21BD72A225KE02, this soft-termination chip multilayer ceramic capacitor (MLCC) is engineered exclusively for highly demanding automotive powertrain and safety equipment applications. By achieving an unprecedented 2.2μF capacitance at a 100Vdc rating within a remarkably small 0805-inch (2.0 × 1.25mm) footprint, Murata Manufacturing Co., Ltd. has established a new global benchmark for passive electronic components.
As the automotive industry experiences a rapid acceleration in vehicle electrification, the demand for highly efficient, miniaturized components has never been higher. Autonomous driving (AD) systems and advanced driver-assistance systems (ADAS) are growing increasingly sophisticated with each passing year. Consequently, automotive engineers are placed under immense pressure to integrate a vast array of new functionalities into extremely tight printed circuit board (PCB) spaces. The introduction of this newly optimized component directly resolves this spatial bottleneck, allowing for maximum performance without compromising on board real estate.
Addressing the Shift to 48V Power Architectures
Modern vehicle designs are swiftly transitioning toward 48V power systems to handle the increased electrical loads of next-generation features. These upgraded systems inherently require electronic components that can seamlessly blend high capacitance, high voltage tolerance, and a substantially reduced physical footprint. The newly released soft-termination chip MLCC is a perfect fit for these 48V environments. By leveraging Murata’s proprietary ceramic material design, the engineers were able to maintain rigorous fine particle size and uniformity control.
Historically, achieving a 2.2μF capacitance at a 100Vdc rating was entirely restricted to the significantly larger 1206-inch (3.2 × 1.6mm) MLCC packages. By successfully scaling this performance down to the 0805-inch category, Murata has provided developers with an incredibly powerful tool for circuit miniaturization.

Overcoming Mechanical Stress and Board Flexure
One of the most persistent reliability concerns in automotive engineering is the mechanical stress exerted on electrical components. Vehicles operate in harsh physical environments, subjecting internal electronics to constant vibration, thermal cycling, and physical shocks. These factors frequently lead to board flexure, which can easily induce post-mount cracking in standard rigid capacitors.
To combat this critical issue, this MLCC utilizes an advanced soft-termination design. This specialized flexible termination layer actively absorbs the mechanical stresses associated with board bending and thermal expansion. The resulting enhancement in field reliability ensures that vital safety systems and powertrain control units continue to function flawlessly, even under extreme driving conditions.
Dramatic Space Savings and Future Implications
The integration of this new capacitor yields profound space-saving benefits for automotive circuit designers. When placed side-by-side with previous iterations, the advantages become immediately clear:
- 51% Area Reduction: Achieves an approximate 51% decrease in the required board mounting area when compared to Murata’s older 2.2μF/100Vdc solutions.
- 2.2x Capacitance Boost: Delivers an impressive 2.2 times increase in total capacitance over the company’s previous 0805-inch, 100Vdc product line.
- Thermal Resilience: Fully supports an aggressive operating temperature range of -55°C to +125°C, easily satisfying strict X7T temperature characteristics as defined by EIA standards.
Murata remains a worldwide leader in the design, manufacture, and sale of ceramic-based passive electronic components. Through continuous research and development, the company is firmly committed to expanding its automotive-grade MLCC lineup. By consistently delivering the miniaturization, high capacitance, and unyielding reliability required by the industry, Murata is actively shaping the future of transportation.
