MLCC GCM21BL81C105KA58L

What is GCM21BL81C105KA58L MLCC?

The GCM21BL81C105KA58L is an SMD capacitor manufactured by Murata (村田). Key specs include 1µF capacitance, 16V rating, X8L dielectric, and ±10% tolerance in an 0805 package. RoHS compliant, it is designed for high-reliability filtering and decoupling in automotive-grade electronics.

✔ RoHS Compliant  /  ✔ 0805  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Automotive ECUs: The X8L dielectric (up to 150°C) and 16V rating ensure stable capacitance under harsh thermal cycling and voltage variations.
• Power Supply Decoupling: 1µF in 0805 provides low-ESR bypass for digital ICs, minimizing noise on 3.3V or 5V rails.
• ADAS Sensor Modules: Murata’s automotive grade (GCM series) meets AEC-Q200, making this MLCC ideal for safety-critical LiDAR or camera circuits.

Key Features & Advantages

• High Temperature X8L: Stable capacitance from -55°C to +150°C, outperforming standard X7R in engine-compartment designs.
• Compact 0805 Footprint: Saves board space while delivering 1µF – a perfect compromise between size and capacitance density.
• Rigorous Automotive Qualification: Murata’s GCM series undergoes strict reliability testing for vibration, humidity, and thermal shock.

Frequently Asked Questions

1. Q: What makes GCM21BL81C105KA58L different from a standard 0805 1µF X7R?
