What is GCM21BR72A473KA37K MLCC?

The GCM21BR72A473KA37K is a SMD capacitor manufactured by Murata. Key specs include 0.047µF capacitance, 100V rating, X7R dielectric, 0805 package, and ±10% tolerance. RoHS compliant, it is designed for reliable decoupling and filtering in medium-voltage circuits.

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

Typical Applications & Why This Part Fits

• Power supply bypass: The 100V rating and X7R stability make it ideal for smoothing ripple on 48V or 72V telecom rails.
• DC-DC converter output filtering: 0.047µF at 100V fits snubber or feedback compensation networks in compact 0805 footprint.
• Automotive sensor modules: Murata’s AEC-Q200 grade and tight tolerance ensure consistent performance under temperature extremes.

Key Features & Advantages

• 100V Dielectric Strength: Supports higher voltage designs without requiring larger case sizes, saving PCB space.
• X7R Temperature Stability: Capacitance change within ±15% from -55°C to +125°C, suitable for industrial and automotive environments.
• 0805 Industry Standard Footprint: Easy to assemble and compatible with common pick-and-place machines for streamlined production.
