Functions

General Description

This is a high-capacitance, high-voltage, vibration and high-temperature resistant capacitor for voltage regulation and filtering. It is specially designed for PCBs exposed to vibration, bending and high temperature, featuring high crack resistance and long service life.

Technical Functions

1. Voltage Regulation & Energy Storage: Stabilize output voltage and suppress surge voltage at the output of DC-DC converters, LDOs and power modules.

2. High-frequency Filtering & Decoupling: Eliminate power ripples and high-frequency noise to supply clean power for MCUs, SoCs and automotive ICs.

3. Anti-cracking against PCB Bending: The resin-based soft termination absorbs bending stress of PCBs and prevents ceramic body cracking, a common failure of conventional MLCCs on large, thin or vibrating circuit boards.

4. Vibration & Shock Resistance: Ensures stable performance in long-term harsh vibration environments for automotive and industrial equipment.

5. Temperature Compensation: X7S dielectric maintains stable capacitance across -55℃ to +125℃, ideal for high-temperature working conditions.

Application Coverage

• Automotive Electronics (Core Application): AEC-Q200 certified. Applicable to powertrain systems, safety-related ECUs, BMS, on-board chargers, vehicle central control, car lights and ADAS systems.

• Industrial Control: PLCs, servo drives, industrial power supplies, main control boards and robots (for heavy vibration, high temperature and large thin PCBs).

• New Energy Equipment: Energy storage PCS, inverters, charging piles, PV and wind power control boards.

• Communication & Servers: 5G base stations, server power supplies and high-power modules (for high current and large ripples).

• Medical Devices: Power supplies for premium medical equipment and patient monitors (high reliability & long lifespan required).

Recommended Application Scenarios

Preferred for GCJ Soft-Termination MLCC

• Large-sized or thin PCBs prone to bending (conventional MLCCs tend to crack during reflow soldering or under vibration).

• Severe vibration environments in automotive and industrial fields (near engines, chassis and motor control units).

• Long-term operating temperature above 85℃.

• High-current power circuits with large ripples (10μF/50V for secondary side voltage regulation).

• Projects requiring ultra-high reliability with zero tolerance to field failures (automotive, industrial and medical applications).

Not Recommended

• General consumer electronics such as power banks and remote controllers (GRM series is more cost-effective).

• Small packages (0402/0603), low voltage (≤25V) and low-current circuits.

Summary

Murata GCJ32EC71H106KA01L is a 1210 10μF/50V X7S automotive grade soft-termination MLCC. It excels at anti-bending, anti-vibration and high temperature resistance with superior reliability. It is the preferred solution for voltage regulation and filtering in high-stress power circuits of automotive, industrial and new energy devices, effectively solving the cracking and failure issues of ordinary MLCCs.
