MLCC GRM42A7U3F220JW31L

What is GRM42A7U3F220JW31L MLCC?

The GRM42A7U3F220JW31L is a high-voltage SMD multilayer ceramic capacitor from Murata. Key specs include 22 pF capacitance, 3.15 kV DC voltage rating, U2J dielectric, and ±5% tolerance in the 1808 package. Its U2J material delivers stable capacitance over temperature and voltage, making it ideal for demanding high-voltage decoupling and filtering.

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

Typical Applications & Why This Part Fits

• High-Voltage DC-DC Converters: The 3.15 kV rating ensures reliable operation in industrial power supplies where voltage spikes and isolation are critical.
• Snubber Circuits in Switching Power Supplies: Low ESR and stable U2J characteristics damp ringing without degrading over time, even under repetitive high-voltage stress.
• RF Coupling & Impedance Matching: U2J’s low temperature coefficient and tight ±5% tolerance preserve signal integrity in high-frequency communication modules and test equipment.

Key Features & Advantages

• 3.15 kV Rating: Handles extreme voltage requirements in a compact 1808 package, reducing PCB footprint and enabling denser layouts.
• U2J Dielectric: Offers excellent capacitance stability across temperature and voltage compared to X7R or X5R, with very low aging and minimal microphonics.
• ±5% Tight Tolerance: Ensures consistent performance in precision circuits such as timers, filters, and voltage references.

Frequently Asked Questions

1. Q: What makes GRM42A7U3F220JW31L different from a standard MLCC?
