RoHS compliant, it is designed for high-frequency stability and low drift in critical RF and timing circuits.

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

Typical Applications & Why This Part Fits

• RF Impedance Matching Networks: The extremely tight ±0.05pF tolerance and C0G/NP0 stability ensure resonant circuits stay on frequency across temperature, critical for 2.4 GHz and 5 GHz radios.
• TCXO and VCO Frequency-Setting Circuits: With 9.7 pF and 50V rating, this capacitor provides the precise, low-drift capacitance needed for oscillator tank circuits in GPS and base station equipment.
• High-Speed SerDes Coupling: The small 0402 package combined with 9.7 pF value allows DC blocking in 10 Gbps+ differential lanes while minimizing parasitic inductance and maintaining signal integrity.

Key Features & Advantages

• ±0.05pF Ultra-Tight Tolerance: Enables repeatable circuit performance without manual tuning, saving production time and reducing yield loss.
• C0G/NP0 Temperature Stability: Capacitance changes less than ±30 ppm/°C, ensuring consistent filter and oscillator behavior from -55°C to +125°C.
• 50V DC Rating in 0402 Size: Provides margin for bias-voltage derating, making the part robust against voltage surges in portable and IoT designs.

Frequently Asked Questions

1. Q: What makes GJM1555C1H9R7WB01D different from a standard 0402 capacitor?
