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

Typical Applications & Why This Part Fits

• High-Frequency RF Circuits: The C0G/NP0 dielectric provides extremely low ESR and stable capacitance over temperature and voltage, ideal for impedance matching and decoupling in RF front ends.
• Precision Timing Networks: With ±5% tolerance and near-zero aging, this 0.022μF capacitor supports accurate RC time constants in oscillator and delay circuits.
• Sensor Interface Filtering: The 50V rating offers headroom for supply rails in industrial sensor modules, while the small 0805 footprint saves board space.

Key Features & Advantages

• C0G/NP0 Stability: Capacitance change within ±30ppm/°C, ensuring reliable performance across -55°C to +125°C.
• High Voltage Rating: 50V withstand in a compact 0805 body enables use in 12V/24V systems without derating concerns.
• Tight ±5% Tolerance: Reduces design margin requirements in filter and timing applications, improving yield.

Frequently Asked Questions

1. Q: What makes GRM21B5C1H223JA01K different from a standard X7R capacitor?
