MLCC GRM31BR72J472KW01L

What is GRM31BR72J472KW01L MLCC?

The GRM31BR72J472KW01L is a SMD capacitor manufactured by Murata. Key specs include 4700pF capacitance, 630V DC rating, X7R dielectric, 1206 package, and ±10% tolerance. RoHS compliant, it is designed for high-voltage and reliable decoupling in power electronics.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 630V rating provides ample headroom for high-voltage rails, while the X7R dielectric ensures stable capacitance over temperature.
• Snubber Circuits in Switching Supplies: Its low ESR and tight tolerance (±10%) help suppress voltage spikes reliably in 1206 footprint.
• Industrial Control Modules: The robust X7R performance from -55°C to +125°C matches harsh environment requirements, and the compact size saves board space.

Key Features & Advantages

• High Voltage Rating (630V): Enables use in power stages and protection circuits where standard 50V MLCCs would fail.
• X7R Dielectric: Capacitance change within ±15% over wide temperature range, ideal for bypass and coupling.
• 1206 Package: Balances high-voltage capability with small footprint, simplifying layout in dense designs.
