MLCC GQM1555C2DR90WB01D

What is GQM1555C2DR90WB01D MLCC?

The GQM1555C2DR90WB01D is a high-voltage SMD capacitor manufactured by Murata. Key specs include 0.9pF capacitance, 200V DC rating, NP0 (C0G) dielectric, and ±0.05pF tolerance in an 0402 package. RoHS compliant, it is designed for precise, stable RF and high-voltage decoupling applications.

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

Typical Applications & Why This Part Fits

• RF Tuning & Impedance Matching: The ultra-low 0.9pF value with ±0.05pF tolerance enables fine frequency adjustment in narrowband filters, VCOs, and antenna matching networks where Murata’s NP0 stability is critical.
• High-Voltage DC-DC Converters: With a 200V rating, this MLCC safely handles flyback snubber or bootstrap capacitor roles in compact power modules, despite its tiny 0402 footprint.
• Sensor Interface Circuits: The tight tolerance and low drift of NP0 ensure consistent parasitic capacitance in high-impedance nodes of proximity or capacitive sensors operating at elevated voltages.

Key Features & Advantages

• Ultra-Tight Tolerance of ±0.05pF: Delivers precise and repeatable capacitance value, essential for high-frequency and measurement applications.
• High 200V Voltage Rating: Allows safe operation in circuits with rail voltages beyond typical 50V/100V limits, adding design margin.
• Stable NP0 (C0G) Dielectric: Offers near-zero capacitance change over temperature (-55°C to +125°C) and negligible aging, ideal for timing and filter networks.
