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

Typical Applications & Why This Part Fits

• Power Supply Decoupling: With 47µF capacitance and 10V rating, it effectively suppresses switching noise and ripple on 3.3V or 5V rails, stabilizing high-speed ICs.
• DC/DC Converter Output Smoothing: The X7T dielectric maintains stable capacitance over temperature, ensuring smooth output in portable electronics and industrial modules.
• Battery-Powered Devices: Its low ESR and small 1210 footprint make it ideal for bulk storage in smartphones, wearables, and IoT sensors, saving board space while providing 47µF hold-up energy.

Key Features & Advantages

• High Capacitance in 1210 Package: 47µF in a compact SMD body reduces PCB footprint, enabling denser designs without compromising performance.
• Stable X7T Dielectric: Offers better capacitance stability over voltage and temperature than X5R, with low aging rate and reliable operation up to +125°C.
• ±10% Tight Tolerance: Allows precise capacitance matching in timing circuits and LDO output stages, minimizing design margins.

Frequently Asked Questions

1. Q: What makes GRM32ED71A476KE15L different from a standard X7R capacitor?
   A: This part uses Murata’s X7T dielectric, which provides tighter capacitance change limits (±15% over -55°C to +125°C) compared to standard X7R (±15% typical but with different curves), ensuring more predictable performance under temperature extremes.
2. Q: Is GRM32ED71A476KE15L 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 — ideal for both evaluation and production.
