MLCC GQM2195C2E3R0BB12D

What is GQM2195C2E3R0BB12D MLCC?

The GQM2195C2E3R0BB12D is a high-Q, ultra-low capacitance SMD capacitor manufactured by Murata. Key specs include 3pF capacitance, 250V voltage rating, NP0 (C0G) dielectric, and a tight ±0.1pF tolerance. RoHS compliant, it is designed for precision RF tuning and high-frequency stability.

✔ RoHS Compliant  /  ✔ 0805 Package  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• RF Impedance Matching Networks: The 3pF nominal value with ±0.1pF tolerance ensures precise tuning of input and output matching circuits in LNA and PA stages for low insertion loss.
• VCO & PLL Loop Filters: NP0 dielectric provides near-zero capacitance drift over temperature, maintaining stable oscillator frequency in wireless infrastructure equipment.
• High-Voltage Coupling/DC-Blocking: Rated at 250V, this capacitor reliably blocks DC while passing RF signals in transmitter output stages without voltage breakdown risk.

Key Features & Advantages

• Ultra-Tight Tolerance (±0.1pF): Enables consistent circuit resonance without manual trimming, reducing calibration time during production.
• NP0 (C0G) Temperature Stability: Capacitance change is virtually zero across -55°C to +125°C, critical for timing and filter circuits in harsh environments.
• High Self-Resonant Frequency (SRF): The 3pF value combined with 0805 package yields a high SRF, suitable for applications up to several GHz.

Frequently Asked Questions

1. Q: What makes GQM2195C2E3R0BB12D different from a standard 0805 MLCC?
