MLCC GRM21BR72A474MA73L

What is GRM21BR72A474MA73L MLCC?

The GRM21BR72A474MA73L is a multilayer ceramic capacitor (MLCC) manufactured by Murata. Key specs include 0.47µF capacitance, 100V DC rating, X7R dielectric, 0805 package, and ±20% tolerance. RoHS compliant, it is designed for high-voltage decoupling and bypass applications requiring stable capacitance over temperature.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Input/Output Filtering: The 0.47µF capacitance combined with a 100V rating effectively reduces ripple and noise in high-voltage power rails.
• Industrial Sensor Interfaces: X7R dielectric ensures ±15% capacitance change from -55°C to +125°C, maintaining signal integrity in harsh environments.
• Telecom Base Station Power Supplies: The 0805 package allows dense PCB layouts while the 100V rating provides ample margin for unregulated bus voltages.

Key Features & Advantages

• High Voltage Rating (100V): Enables safe operation in circuits with voltage surges up to 100V without derating concerns.
• X7R Temperature Stability: Capacitance variation within ±15% over -55°C to +125°C, ideal for automotive and industrial temperature ranges.
• Compact 0805 Footprint: Saves board space while delivering 0.47µF, reducing overall design size.

Frequently Asked Questions

1. Q: What makes GRM21BR72A474MA73L different from a standard 0805 MLCC?
   A: Its 100V voltage rating is significantly higher than typical 25V or 50V parts, allowing use in higher-voltage circuits without series stacking.
2. Q: Is GRM21BR72A474MA73L RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
3. Q: What is the MOQ? Can we get small batches?
   A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply and flexible quantities for pre-production runs.
