What is GRM188D72A105KE01D MLCC?

The GRM188D72A105KE01D is an SMD capacitor manufactured by Murata. Key specs include 1µF capacitance, 100V rating, X7T dielectric, and a 0603 package with ±10% tolerance. RoHS compliant, it is designed for reliable high-voltage decoupling and filtering in space-constrained circuits.

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

Typical Applications & Why This Part Fits

• Automotive ECU Power Rails: The 100V rating and X7T stability ensure steady decoupling under harsh voltage transients, while the compact 0603 size fits dense board layouts.
• Industrial DC-DC Converters: 1µF capacitance at 100V smooths output ripple efficiently, and the ±10% tolerance maintains consistent filtering performance over temperature.
• Base Station Power Supplies: X7T dielectric offers low capacitance variation across -55°C to +125°C, critical for long-term reliability in telecom infrastructure.

Key Features & Advantages

• High Voltage in Small Footprint: Achieves 100V rating in a 0603 body, allowing designers to meet safety margins without sacrificing board area.
• X7T Temperature Stability: Provides predictable capacitance behavior across a wide temperature range, reducing derating concerns in thermal cycling.
• Tight ±10% Tolerance: Enables precise filtering and timing circuits, minimizing design iterations and component matching effort.

Frequently Asked Questions

1. Q: What makes GRM188D72A105KE01D different from a standard 0603 MLCC?
   A: Its key differentiator is the combination of 1µF capacitance and 100V rating in an X7T dielectric, which provides higher voltage margin and better temperature stability than general-purpose X5R parts of the same size.
2. Q: Is GRM188D72A105KE01D 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 and flexibility for low-volume validation.
