MLCC GRM188D71H105ME01J

What is GRM188D71H105ME01J MLCC?

The GRM188D71H105ME01J is a multilayer ceramic capacitor manufactured by Murata. Key specs include 1 µF capacitance, 50 V voltage rating, X7T dielectric, 0603 package, and ±20% tolerance. RoHS compliant, it is designed for high-reliability decoupling and filtering in space-constrained circuits.

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

Typical Applications & Why This Part Fits

• Power Rail Decoupling: The 1 µF capacitance combined with 50 V rating provides effective noise suppression on 3.3 V to 12 V rails, while the X7T dielectric ensures stable performance across -55°C to +125°C.
• DC-DC Converter Output Filtering: Its low equivalent series resistance (ESR) and small 0603 footprint allow dense placement near switching regulators, reducing output ripple.
• Automotive & Industrial Sensors: The 50 V tolerance and X7T temperature characteristics make it suitable for harsh environments with voltage transients, such as sensor power bypass.

Key Features & Advantages

• High Voltage Rating: 50 V rating in a 0603 case enables robust design without sacrificing board space.
• X7T Dielectric Stability: Exhibits only ±15% capacitance change over temperature, offering better stability than general-purpose X5R parts.
• Lead-Free & RoHS Compliant: Fully compliant with lead‑free soldering processes and environmental regulations.

Frequently Asked Questions

1. Q: What makes GRM188D71H105ME01J different from a standard 0603 X7R capacitor?
   A: The “D” series denotes Murata’s X7T dielectric, which guarantees tighter capacitance variation (±15% vs ±15% for X7R, but with improved DC bias characteristics). Additionally, the 50 V rating in this small package requires specialized construction, ensuring long-term reliability under voltage stress.
2. Q: Is GRM188D71H105ME01J 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.
