MLCC GCM21BL81H334KA56L

What is GCM21BL81H334KA56L MLCC?

The GCM21BL81H334KA56L is a surface-mount multilayer ceramic capacitor manufactured by Murata (村田). Key specs include 0.33µF capacitance, 50V voltage rating, X8L dielectric, and ±10% tolerance. RoHS compliant, it is designed for high-reliability circuits requiring stable capacitance under extreme temperatures.

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

Typical Applications & Why This Part Fits

• Automotive ECU & Sensor Modules: The X8L dielectric (−55°C to +150°C) ensures capacitance stability within ±10% under under‑hood thermal cycling, while the 0805 footprint supports dense PCB layouts.
• High‑Performance LED Drivers: With 50V withstand and 0.33µF filtering, this cap smooths ripple in LED strings, resisting self‑heating and maintaining low ESR over life.
• Industrial Power Management: The ±10% tolerance guarantees predictable decoupling at 50V rails, and the 0805 package allows replacement of larger capacitors with no layout change.

Key Features & Advantages

• X8L Temperature Characteristic: Capacitance change within ±15% from −55°C to +150°C, outperforming X7R—ideal for hot environments.
• 50V Rated Voltage: Handles 24V/48V industrial buses with safety margin, reducing failure risk from voltage transients.
• 0805 Compact Size: Saves space on high‑density boards while maintaining 0.33µF: enables higher component count per unit area.

Frequently Asked Questions

1. Q: What makes GCM21BL81H334KA56L different from a standard X7R MLCC?
   A: It uses X8L dielectric, which operates up to 150°C (vs. 125°C for X7R) and offers tighter capacitance stability over the full temperature range, making it essential for automotive and industrial high‑temperature zones.
2. Q: Is this part 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—ideal for both low‑volume R&D and medium‑run production.
