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

Typical Applications & Why This Part Fits

• DC-DC Converter Snubber Circuits: The 250V rating and ultra-stable C0G/NP0 dielectric ensure consistent snubbing without capacitance shift under bias, critical for reducing EMI in power modules.
• Sensor Interface Filtering: Tight ±5% tolerance maintains precise time constants in capacitive sensor front-ends, while the low ESR of 0805 package minimizes noise floor at high frequencies.
• Automotive CAN Bus Line Termination: Murata’s automotive-grade qualification guarantees long-term reliability over -55°C to +125°C, and the 330pF value provides optimal common-mode filtering for high-speed differential lines.

Key Features & Advantages

• Ultra-Stable C0G/NP0 Dielectric: No voltage or temperature coefficient variation (±30ppm/°C) ensures capacitance remains 330pF ±5% under full 250V bias, essential for precision timing circuits.
• High Voltage Rating in Compact 0805: 250V withstand in a 2.0×1.25mm footprint saves board space compared to higher voltage case sizes, enabling denser power supply designs.
• Automotive-Grade Reliability: Murata’s GCM series undergoes rigorous AEC-Q200 testing, providing 3x margin against flex cracks and moisture resistance for under-hood applications.

Frequently Asked Questions

1. Q: What makes GCM21A5C2E331JX01D different from a standard 0805 330pF capacitor?
   A: This Murata part combines a 250V voltage rating with C0G/NP0 stability in an 0805 package—most standard 0805 MLCCs are limited to 50V or 100V, whereas this ensures no capacitance derating up to 250V.
2. Q: Is GCM21A5C2E331JX01D 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 with flexible volume for this automotive-grade capacitor.
