MLCC GJM1555C1H5R4WB01D

What is GJM1555C1H5R4WB01D MLCC?

The GJM1555C1H5R4WB01D is an SMD capacitor manufactured by Murata. Key specs include 5.4 pF capacitance, 50 VDC rating, C0G/NP0 dielectric, and a tight ±0.05 pF tolerance in the 0402 case size. RoHS compliant, it is designed for high-frequency stability and precision timing circuits.

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

Typical Applications & Why This Part Fits

• RF Matching Networks: The 5.4 pF value and ±0.05 pF ultra-tight tolerance ensure precise impedance matching in 50 Ω RF paths for LNA and antenna tuner stages.
• Oscillator & PLL Loop Filters: C0G/NP0 provides near-zero capacitance change with voltage, locking VCO frequencies with minimal drift across the 50 V bias range.
• High-Speed Digital Decoupling: Low ESR at GHz frequencies due to the 0402 package and C0G construction effectively suppresses noise on high-speed clock and data lines.

Key Features & Advantages

• Ultra-Stable C0G/NP0 Dielectric: Capacitance change is less than ±0.3% over temperature from -55°C to +125°C, eliminating derating calculations.
• ±0.05 pF Tight Tolerance: Enables repeatable circuit performance without trimming, reducing calibration steps in production.
• 50 V Rated Voltage: Provides a safety margin for 3.3 V, 5 V, and even 12–48 V bias lines without voltage coefficient effects.

Frequently Asked Questions

1. Q: What makes GJM1555C1H5R4WB01D different from a standard 0402 capacitor?
