MLCC GRM31A5C3A220JW01D

What is GRM31A5C3A220JW01D MLCC?

The GRM31A5C3A220JW01D is a SMD Capacitor manufactured by Murata. Key specs include 22pF (±5%) capacitance, 1kV rated voltage, C0G/NP0 dielectric, and 1206 package. RoHS compliant, it is designed for high-voltage, high-stability filtering and timing applications.

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

Typical Applications & Why This Part Fits

• High-Voltage DC-DC Converters: The 1kV rating ensures reliable decoupling in boost or flyback stages where voltage spikes exceed 500V.
• Snubber Circuits in Power Inverters: C0G/NP0 dielectric provides negligible capacitance drift under DC bias, critical for consistent ring suppression.
• RF Impedance Matching: Tight ±5% tolerance and stable temperature coefficient (0±30ppm/°C) preserve resonant frequency accuracy in filters.

Key Features & Advantages

• High Voltage Rating (1kV): Enables direct use in primary-side circuits without derating concerns, reducing component count.
• C0G/NP0 Dielectric: Extremely low capacitance change vs. temperature, voltage, and frequency—ideal for precision timing.
• 1206 Package: Balanced power handling and solder joint reliability for demanding automotive and industrial PCBs.
