MLCC GRM21A5C2E821JWA1J

What is GRM21A5C2E821JWA1J MLCC?

The GRM21A5C2E821JWA1J is a high-voltage SMD capacitor manufactured by Murata. Key specs include 820pF capacitance, 250V DC rating, C0G/NP0 dielectric, ±5% tolerance, and an 0805 package. RoHS compliant, it is designed for stable performance in demanding circuits.

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

Typical Applications & Why This Part Fits

• High-frequency decoupling: 820pF ±5% at 250V provides reliable bypassing for noise-sensitive RF and power modules.
• Resonant circuits: C0G/NP0 ensures near-zero capacitance drift over temperature, critical for LC oscillators and filters.
• Timing/filtering networks: The 250V rating exceeds standard 50V/100V needs, offering headroom in industrial power supplies.

Key Features & Advantages

• C0G/NP0 dielectric: Ultra-stable capacitance with ±30ppm/°C TCC, ideal for precision circuits.
• 250V voltage rating: Supports high-voltage rails and bus capacitors without derating concerns in 0805 size.
• ±5% tight tolerance: Enables consistent performance in stringent filter and oscillator designs.

Frequently Asked Questions

1. Q: What makes GRM21A5C2E821JWA1J different from a standard 0805 MLCC?
   A: Its C0G/NP0 material provides extremely low capacitance change vs. temperature and voltage, unlike X7R or X5R, and the 250V rating is unusually high for this footprint.
2. Q: Is GRM21A5C2E821JWA1J 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.
