MLCC GCM219R72A393KA37J

What is GCM219R72A393KA37J MLCC?

The GCM219R72A393KA37J is a multilayer ceramic capacitor (MLCC) manufactured by Murata. Key specs include a capacitance of 0.039µF, rated voltage of 100V, X7R dielectric, 0805 package size, and ±10% tolerance. RoHS compliant, it is designed for reliable decoupling and filtering in space-constrained, high-voltage circuits.

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

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: The 100V rating and 0.039µF capacitance provide effective ripple suppression in 48V or 72V bus converters, while the 0805 footprint fits dense PCB layouts.
• Automotive CAN Bus Line Filtering: Murata’s GCM series is AEC-Q200 qualified; the stable X7R dielectric ensures consistent –55°C to +125°C operation, and the ±10% tolerance meets bus decoupling requirements.
• Industrial Sensor Power Rail Decoupling: With X7R’s low capacitance change under DC bias and the 0805 size, this capacitor delivers predictable performance in 12V–24V sensor modules, minimizing noise.

Key Features & Advantages

• High Voltage in Compact Footprint: Achieves 100V rating within an 0805 case, saving board space compared to larger packages.
• Stable X7R Dielectric: Maintains capacitance within ±15% over –55°C to +125°C, ensuring reliability across temperature extremes.
• Murata Proven Quality: Rigorous testing and long-term supply guarantee consistent performance for automotive and industrial designs.
