MLCC GJM1555C1H3R0WB01D

What is GJM1555C1H3R0WB01D MLCC?

The GJM1555C1H3R0WB01D is a high-precision SMD Capacitor manufactured by Murata. Key specs include 3pF capacitance, 50V rated voltage, C0G/NP0 dielectric, and an ultra-tight tolerance of ±0.05pF in the compact 0402 package. RoHS compliant, it is designed for RF and high-frequency circuits requiring minimal capacitance drift.

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

Typical Applications & Why This Part Fits

• RF Impedance Matching Networks: The ±0.05pF tolerance ensures precise resonance tuning in 50Ω systems, reducing return loss for Wi-Fi and Bluetooth front-ends.
• Crystal Oscillator Load Capacitors: C0G/NP0’s negligible voltage coefficient (VCC) maintains stable oscillation frequency across supply variations, critical for MCU clock circuits.
• High-Frequency Decoupling in IoT Modules: 3pF at 50V provides effective noise bypass above 1 GHz, while the 0402 size fits densely populated PCB layouts for wearable sensors.

Key Features & Advantages

• Ultra-Tight Tolerance ±0.05pF: Offers 5× better accuracy than standard ±0.1pF MLCCs, minimizing calibration steps in precision analog filters.
• C0G/NP0 Temperature Stability: Capacitance changes less than ±30ppm/°C from -55°C to +125°C, ensuring reliable performance in automotive or outdoor base stations.
• Low ESR & High Self-Resonant Frequency (SRF): Murata’s GJM series delivers SRF >5 GHz, ideal for mmWave antenna tuning and 5G NR sub-6 GHz paths.

Frequently Asked Questions

1. Q: What makes GJM1555C1H3R0WB01D different from a standard 3pF C0G MLCC?
   A: It features Murata’s “GJM” high-Q process with ±0.05pF tolerance and tighter capacitance drift, compared to general-purpose GRM-grade parts with ±0.25pF or ±10% tolerance.
