What is GCM21BR7YA684KA55L MLCC?

The GCM21BR7YA684KA55L is a SMD capacitor manufactured by Murata. Key specs include 0.68µF capacitance, 35V voltage rating, X7R dielectric, 0805 package, and ±10% tolerance. RoHS compliant, it is designed for stable decoupling and filtering in space-constrained circuits.

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

Typical Applications & Why This Part Fits

• DC-DC converter output smoothing: The 0.68µF capacitance combined with 35V rating effectively reduces ripple in moderate-power converters where board space is limited.
• I/O line bypass filtering: X7R stability over temperature (-55°C to +125°C) ensures consistent decoupling performance for digital interface lines in industrial environments.
• Automotive body electronics: With Murata’s automotive-grade reliability and 0805 footprint, this MLCC suits ECUs, sensors, and infotainment modules requiring robust mid-value capacitance.

Key Features & Advantages

• 0.68µF ±10% @ 35V: Offers a balance between energy storage density and voltage margin, fitting designs where 0.1µF is insufficient but 1µF is overkill.
• X7R dielectric: Provides ±15% capacitance change over -55°C to +125°C, ensuring predictable behavior across automotive and industrial temperature ranges.
• 0805 package: Occupies minimal PCB area while supporting hand-soldering or automated assembly, reducing overall system footprint.
