What is GCM21BR71H105MA03L MLCC?
The GCM21BR71H105MA03L is a high‑reliability SMD capacitor manufactured by Murata. Key specs include a capacitance of 1 µF, rated voltage 50 V, X7R dielectric, and an 0805 package with ±20% tolerance. RoHS compliant, it is designed for stable decoupling and filtering in automotive and industrial circuits.
✔ RoHS Compliant / ✔ 0805 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Automotive ECU power rails: The 50 V rating and X7R temperature stability (‑55°C to +125°C) ensure reliable bulk decoupling under harsh under‑hood conditions.
- Industrial sensor modules: With 1 µF capacitance and ±20% tolerance, it provides sufficient local energy storage for microcontrollers and ADCs without over‑specifying precision.
- DC‑DC converter output filtering: The 0805 footprint balances board space and ESL performance, making it ideal for low‑profile power supplies where ceramic capacitors are preferred.
Key Features & Advantages
- High Voltage Safety Margin: 50 V rating allows de‑rating in 24 V and 48 V systems, improving long‑term reliability.
- Automotive Grade Construction: Murata’s GCM series undergoes rigorous AEC‑Q200 qualification, reducing failure risk in safety‑critical designs.
- Compact 0805 Size: Occupies minimal PCB area while delivering 1 µF, enabling dense layout for multi‑layer boards.
