What is GCQ1555C1HR18BB01D MLCC?
The GCQ1555C1HR18BB01D is an SMD capacitor manufactured by Murata. Key specs include 0.18PF capacitance, 50V voltage rating, C0G/NP0 dielectric, and ±0.1pF tolerance in an 0402 package. RoHS compliant, it is designed for ultra-precision RF and high-frequency coupling where minimal capacitance drift is critical.
✔ RoHS Compliant / ✔ 0402 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Impedance Matching Networks: The 0.18PF ±0.1pF ultra-low value with C0G/NP0 stability enables precise resonant circuit tuning without temperature-induced variance.
- High-Speed Signal Conditioning: 50V breakdown margin and 0402 footprint allow placement near sensitive I/O lines in compact wireless modules or test equipment.
- Oscillator Feedback Loops: The tight ±0.1pF tolerance ensures consistent oscillation frequency in VCO and PLL designs, eliminating the need for manual trimming.
Key Features & Advantages
- Ultra-Low 0.18pF Value: Enables virtually lossless decoupling at GHz frequencies where even 1pF would load the signal path.
- C0G/NP0 Dielectric: Near-zero capacitance change across temperature and voltage, providing predictable performance in precision analog and RF circuits.
- 0402 Miniature Package: Saves PCB real estate in space-constrained designs such as IoT sensors, wearables, and handheld testers.
Frequently Asked Questions
