MLCC GCM21BR91H104KA37L

What is GCM21BR91H104KA37L MLCC?

The GCM21BR91H104KA37L is a high-temperature X8R SMD capacitor manufactured by Murata. Key specs include 0.1µF capacitance, 50V rating, ±10% tolerance, and an 0805 package. RoHS compliant, it is designed for reliable DC blocking and decoupling in 150°C capable automotive and industrial circuits.

✔ RoHS Compliant  /  ✔ 0805 Package  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Engine Control Units (ECU): The X8R dielectric (rated to 150°C) together with 50V withstand voltage ensures stable filtering of sensor signals under extreme under‑hood heat.
• LED Automotive Lighting: 0.1µF in 0805 footprint provides effective bypass for PWM‑driven LED modules while saving PCB space alongside power ICs.
• Industrial Power Supplies: Tight ±10% tolerance guarantees consistent decoupling performance across the 50V rail, reducing ripple in high‑reliability converters.

Key Features & Advantages

• High‑Temperature X8R Dielectric: Operates continuously at 150°C, exceeding standard X7R limits, making it ideal for harsh environment designs.
• Murata Quality & Long‑Life Construction: Base‑metal electrode (BME) technology and nickel barrier terminations ensure excellent solderability and long‑term reliability.
• Compact 0805 Footprint: Balances capacitance density and ease of assembly, suitable for automated pick‑and‑place and dense layouts.

Frequently Asked Questions

1. Q: What makes GCM21BR91H104KA37L different from a standard 0805 X7R capacitor?
   A: Its X8R dielectric supports operation up to 150°C (vs. 125°C for X7R), critical for automotive under‑hood and other high‑temperature applications, while maintaining the same 50V rating and 0.1µF value.
2. Q: Is GCM21BR91H104KA37L RoHS compliant?
   A: Yes, as a Murata product it is standardly RoHS compliant and lead‑free, meeting EU directive 2011/65/EU.
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. Flexible quantities are available to match your project phase.
