What is GQM1555C2DR50WB01D MLCC?
The GQM1555C2DR50WB01D is a ceramic SMD capacitor manufactured by Murata (村田). Key specs include 0.5pF capacitance, 200V rating, NP0 (C0G) dielectric, and 0402 package size with ±0.05pF tolerance. RoHS compliant, it is designed for high-frequency RF and precision tuning circuits requiring ultra-stable capacitance.
✔ RoHS Compliant / ✔ 0402 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Impedance Matching: The ±0.05pF tight tolerance and NP0 temperature stability ensure precise impedance matching in 200V-rated RF power amplifiers.
- VCO & PLL Tuning Networks: The ultra-low 0.5pF value minimizes parasitic loading, making it ideal for high-frequency oscillator circuits where even 0.1pF variation affects lock range.
- Medical Imaging Transceivers: The 200V withstand capability combined with Class 1 NP0 drift-free performance suits high-voltage bias networks in MRI or ultrasound front-ends.
Key Features & Advantages
- Ultra-Low Capacitance (0.5pF): Enables series coupling in GHz-band circuits where standard MLCCs introduce excessive insertion loss.
- High Voltage (200V) in 0402: Murata’s advanced thin-film process packs 200V withstand into a 0402 land pattern, saving board space in high-density designs.
- NP0 (C0G) Dielectric: Near-zero capacitance change over temperature (-55°C to +125°C) and voltage, eliminating derating worries.
Frequently Asked Questions
- Q: What makes GQM1555C2DR50WB01D different from a standard 0402 capacitor?
A: This Murata GQM series part uses a special RF-grade ceramic body and laser-trimmed electrode to achieve ±0.05pF absolute tolerance at 0.5pF—unattainable with standard EIA 0402 MLCCs. - Q: Is GQM1555C2DR50WB01D RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free. - Q: What is the MOQ? Can we get small batches?
A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply.
