The GRM21A5C2E820JW01D is a precision SMD capacitor manufactured by Murata. Key specs include a capacitance of 82pF, a voltage rating of 250V, a C0G/NP0 dielectric, and a tolerance of ±5%. RoHS compliant, it is designed for high-stability filtering and coupling in medium-voltage circuits.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Snubber Networks: The 250V rating and stable C0G/NP0 dielectric ensure reliable ringing suppression and noise absorption at elevated voltages.
• High-Impedance RF Coupling: The 82pF value provides predictable capacitive reactance at high frequencies, while the low-loss Class I material minimizes signal distortion.
• Sensor Interface Filtering: The tight ±5% tolerance allows precise cutoff frequency design for analog sensor signal chains without recalibration.

Key Features & Advantages

• Class I C0G Stability: Minimal capacitance change over temperature, voltage, and aging – ideal for resonant and timing circuits.
• 250V Rated Voltage: Offers robust headroom for 48V and 120V bus rails, reducing derating complexity.
• Compact 0805 Footprint: Balances high-voltage spacing with space savings in dense mixed-signal layouts.

Frequently Asked Questions

1. Q: What makes GRM21A5C2E820JW01D different from a standard X7R MLCC?
