The GCQ1555C1HR45WB01D is a SMD capacitor manufactured by Murata. Key specs include 0.45pF capacitance, 50V rating, and C0G/NP0 dielectric with ±0.05pF tolerance. RoHS compliant, it is designed for high-frequency stability and precision timing circuits.
✔ RoHS Compliant / ✔ 0402 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Impedance Matching: The ultra-low 0.45pF capacitance with ±0.05pF tight tolerance ensures precise impedance control in 50Ω RF front-end modules.
- High-Speed Signal Coupling: C0G/NP0 dielectric provides flat temperature characteristics and minimal voltage coefficient, preserving signal integrity up to 50V.
- PLL Loop Filters: Ultra-low capacitance values like 0.45pF are essential for minimizing phase noise in phase-locked loop filter designs operating at microwave frequencies.
Key Features & Advantages
- Tight ±0.05pF Tolerance: Enables repeatable circuit performance without tuning, reducing assembly calibration steps.
- 50V Rated Voltage: Provides headroom for 3.3V/5V systems and supports higher bias applications without derating concerns.
- C0G/NP0 Stability: Near-zero capacitance change over temperature (-55°C to +125°C) and no aging drift, ideal for precision timing.
Frequently Asked Questions
- Q: What makes GCQ1555C1HR45WB01D different from a standard 0402 capacitor?
