What is GRM188C71C475ME21D MLCC?

The GRM188C71C475ME21D is a multilayer ceramic capacitor manufactured by Murata (村田). Key specs include 4.7µF capacitance, 16V rated voltage, X7S dielectric, and ±20% tolerance. RoHS compliant, it is designed for high-density decoupling and power-line filtering.

✔ RoHS Compliant  /  ✔ 0603  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Smartphone Power Rails: The 4.7µF capacitance in 0603 package provides stable decoupling for core voltages, with X7S offering better capacitance stability than X5R under DC bias.
• IoT Sensor Modules: 16V rating allows safe operation in battery-powered circuits, while the ±20% tolerance accommodates sensor calibration variations.
• Industrial Control Interfaces: X7S dielectric ensures minimal capacitance drop over -55°C to +125°C range, critical for reliable filtering in harsh environments.

Key Features & Advantages

• Capacitance Density: 4.7µF in 0603 saves board space without sacrificing filtering performance.
• Voltage Headroom: 16V rating provides 2x margin above typical 5V/3.3V rails, reducing failure risk.
• Temperature Stability: X7S offers ±22% capacitance change vs. ±15% for X7R, but with better DC bias performance at higher voltages.

Frequently Asked Questions

1. Q: What makes GRM188C71C475ME21D different from a standard X5R capacitor?
   A: X7S dielectric provides stable capacitance over a wider temperature range (-55°C to +125°C) than X5R (-55°C to +85°C), while offering improved DC bias characteristics at 16V.
2. Q: Is GRM188C71C475ME21D 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.
