MLCC GRJ55DR7LV474KW01K

What is GRJ55DR7LV474KW01K MLCC?

The GRJ55DR7LV474KW01K is a high-voltage, SMD multilayer ceramic capacitor manufactured by Murata. Key specs include a capacitance of 0.47µF, a voltage rating of 630V, X7R dielectric, and a compact 2220 case size with ±10% tolerance. RoHS compliant, it is designed for stable, high-reliability energy storage in demanding circuit environments.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 0.47µF capacitance combined with 630V rating effectively suppresses ripple in high-voltage switch-mode power supplies, while X7R dielectric ensures stable performance across -55°C to +125°C.
• Snubber Circuits for Motor Drives: Its 2220 package handles high pulse currents, and the ±10% tolerance provides predictable clamping in industrial inverter snubber networks, reducing electromagnetic interference.
• Base Stations & Telecom Power Modules: Murata’s consistent quality and the capacitor’s ability to withstand 630V make it ideal for bulk decoupling in 48V telecom rectifiers and higher-voltage bus conditioning.

Key Features & Advantages

• High Voltage & Capacitance Density: Achieves 0.47µF in a 2220 footprint – a space-saving solution for 630V designs compared to using multiple lower voltage caps.
• X7R Temperature Stability: Capacitance change within ±15% over temperature range ensures reliable filter cutoff and decoupling under thermal stress.
• RoHS & Lead-Free Compliance: Fully halogen-free and meets current environmental standards, simplifying global regulatory approvals.

Frequently Asked Questions

1. Q: What makes GRJ55DR7LV474KW01K different from a standard X7R MLCC?
   A: Its elevated 630V voltage rating in a 2220 case allows direct use in higher-voltage rails without derating, while maintaining the same X7R temperature characteristics.
2. Q: Is GRJ55DR7LV474KW01K 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 for design verification.
