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

Typical Applications & Why This Part Fits

• High-Voltage RF Tuning: The 250V rating combined with C0G/NP0 dielectric ensures negligible capacitance change under voltage bias, making it ideal for impedance matching and resonant tank circuits in power amplifiers.
• Precision Timing Circuits: With ±1% tolerance and ultra-stable temperature characteristics, this 22pF capacitor maintains accurate RC time constants in oscillator and PLL designs.
• Sensor Signal Conditioning: The 0805 footprint and low ESR enable clean decoupling of high-impedance sensor outputs while the high breakdown voltage protects against transient peaks.

Key Features & Advantages

• 250V High-Voltage Rating: Provides a robust safety margin in power supply rails, DC-DC converters, and automotive circuits without derating concerns.
• C0G/NP0 Dielectric: Offers near-zero capacitance drift over temperature (-55°C to +125°C) and under DC bias, essential for frequency-critical applications.
• ±1% Tight Tolerance: Eliminates the need for trimming or calibration in precision analog filters, ensuring repeatable circuit performance batch-to-batch.

Frequently Asked Questions

1. Q: What makes GRM21A5C2E220FW01D different from a standard 0805 MLCC?
