✔ RoHS Compliant  /  ✔ 0402  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• RF Tuning & Matching Networks: The ultra-tight ±0.05pF tolerance and stable C0G/NP0 dielectric ensure minimal frequency drift in high-frequency oscillator and filter circuits.
• High-Frequency Decoupling: Low parasitic inductance from the compact 0402 package, combined with the 50V rating, makes it suitable for supply bypass in RF modules and communications equipment.
• Sensor Signal Conditioning: The low capacitance value (2.9pF) and excellent temperature stability enable precise charge coupling in capacitive sensor front-ends without introducing nonlinearity.

Key Features & Advantages

• ±0.05pF Precision Tolerance: Enables tighter design margins for resonant circuits and impedance matching, reducing the need for tuning.
• C0G/NP0 Dielectric: Offers negligible capacitance variation over temperature (−55°C to +125°C) and low voltage coefficient, ideal for timing and filter applications.
• 0402 Miniature Footprint: Saves valuable PCB space while providing reliable performance up to 50V; supports high-density assembly and automated pick-and-place.

Frequently Asked Questions

1. Q: What makes GJM1555C1H2R9WB01D different from a standard MLCC?
