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

Typical Applications & Why This Part Fits

• Automotive Engine Control Units (ECUs): The X8R dielectric (-55°C to +150°C) ensures stable capacitance even under high under‑hood temperatures, matching the 50V rating for robust power line decoupling.
• Industrial DC-DC Converters: Its 0.047µF value provides effective high‑frequency noise filtering, while the 0603 footprint saves PCB space without compromising the 50V safety margin.
• Base Station Power Supplies: The tight ±10% tolerance allows precise timing and filtering circuits, critical for consistent signal integrity in telecom environments.

Key Features & Advantages

• Wide Temperature Range (X8R): Reliable operation from -55°C to +150°C, surpassing standard X7R for demanding thermal cycles.
• Compact 0603 Package: Enables high‑density layouts while maintaining excellent soldering yield and mechanical strength.
• Low Equivalent Series Resistance (ESR): Murata’s advanced ceramic process minimizes power loss and heat generation, extending system lifespan.

Frequently Asked Questions

1. Q: What makes GCM188R91H473KA37D different from a standard X7R capacitor?
