MLCC GRM31CC72A475ME11K

What is GRM31CC72A475ME11K MLCC?

The GRM31CC72A475ME11K is a SMD capacitor manufactured by Murata (村田). Key specs include 4.7µF capacitance, 100V rated voltage, X7S temperature characteristic, 1206 footprint, and ±20% tolerance. RoHS compliant, it is designed for high-voltage decoupling and bulk energy storage in space-constrained power circuits.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 100V rating and 4.7µF value provide sufficient ripple suppression for 48V or 24V bus converters while maintaining a stable X7S dielectric over -55°C to +125°C.
• Automotive ECU Power Rails: Murata’s AEC-Q200 qualification (implied by X7S/1206 construction) and ±20% tolerance suit non-critical bypass tasks where cost-effective bulk capacitance is needed under high-temperature hood environments.
• Industrial Sensor Modules: The compact 1206 package saves board space in 4-20mA loop-powered transmitters, while the 100V headroom protects against voltage transients from long cable runs.

Key Features & Advantages

• High Voltage in Small Footprint: 100V rating in 1206 size enables 4.7µF capacitance without resorting to larger 1210 or 1812 packages, simplifying layout in multi-layer designs.
• X7S Dielectric Stability: Capacitance change within ±22% over -55°C to +125°C ensures predictable filtering performance across extreme temperature swings.
• Lead-Free & RoHS Compliant: Fully compatible with lead-free soldering profiles, meeting global environmental regulations for automotive and industrial exports.

Frequently Asked Questions

1. Q: What makes GRM31CC72A475ME11K different from a standard X7R MLCC?
   A: X7S allows higher capacitance change (±22%) compared to X7R’s ±15%, but offers improved DC bias performance at high voltages—critical for 100V applications where X7R may lose >50% capacitance under bias.
2. Q: Is GRM31CC72A475ME11K 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 with flexible quantities for engineering samples.
