MLCC GQM1555C2DR30WB01D

What is GQM1555C2DR30WB01D MLCC?

The GQM1555C2DR30WB01D is a high-frequency SMD capacitor manufactured by Murata. Key specs include a capacitance of 0.3 pF, a rated voltage of 200 V, NP0 (C0G) dielectric, and a tight tolerance of ±0.05 pF. RoHS compliant, it is designed for RF and microwave circuits where ultra-low capacitance drift and high Q are critical.

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

Typical Applications & Why This Part Fits

• RF Impedance Matching Networks: The 0.3 pF value and ±0.05 pF tolerance enable precise tuning of antenna filter circuits at 200 V, ensuring minimal signal reflection in transmitters.
• High-Frequency Oscillator Tanks: NP0 (Class 1) dielectric guarantees negligible capacitance change with temperature, critical for maintaining frequency stability in VCOs and PLLs.
• DC-Bias Decoupling for MMICs: The 200 V rating provides ample headroom for GaN or GaAs amplifiers operating at high bias voltages, while the 0402 footprint saves board space in dense PA modules.

Key Features & Advantages

• Ultra-Stable NP0 Dielectric: Capacitance change of less than ±30 ppm/°C over -55°C to +125°C, ensuring consistent performance in harsh environments.
• High Voltage Rating in 0402: 200 V capability in a miniature size allows direct use in DC-DC converters and bias lines without derating concerns.
• Tight ±0.05 pF Tolerance: Enables repeatable circuit behavior without the need for manual trimming, reducing assembly time and costs.
