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

Typical Applications & Why This Part Fits

• Power Supply Decoupling: The 250V rating and X7R stability make this capacitor ideal for smoothing voltage rails in high-voltage DC‑DC converters and inverter modules.
• Automotive Electronics: With 250V withstand capability and 3300pF filtering value, this MLCC suits engine control units and battery management systems requiring robust ceramic capacitors.
• Industrial Sensor Interfaces: The 0805 form factor and ±10% tolerance provide reliable noise filtering for analog sensor inputs in PLCs and motor drives.

Key Features & Advantages

• High Voltage Handling (250V): Allows direct use in 48V–200V bus rails without needing series stacks, saving board space.
• Stable X7R Ceramic: Capacitance varies only ±15% over –55°C to +125°C, ensuring consistent filtering across temperature extremes.
• Compact 0805 Size: Standard footprint simplifies pick-and-place assembly while maintaining adequate voltage endurance for compact industrial designs.

Frequently Asked Questions
