What is GJM1555C1H5R9WB01D MLCC?
The GJM1555C1H5R9WB01D is a precision SMD capacitor manufactured by Murata. Key specs include 5.9pF capacitance, 50V rating, C0G/NP0 dielectric, and ±0.05pF tolerance. RoHS compliant, it is designed for high-frequency stability and tight-tolerance signal conditioning.
✔ RoHS Compliant / ✔ 0402 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Matching Networks: The 5.9pF value with ±0.05pF ultra-tight tolerance ensures precise impedance matching in 50Ω RF front-ends, minimizing return loss.
- PLL Loop Filters: C0G/NP0 dielectric provides nearly zero voltage and temperature coefficient, keeping charge-pump loop filter poles stable across -55°C to +125°C.
- Portable Wireless Modules: 0402 footprint saves PCB real estate in IoT and Bluetooth modules, while 50V rating offers ample headroom for battery-powered rails.
Key Features & Advantages
- Ultra-Tight Tolerance ±0.05pF: Enables accurate capacitance in high-Q resonant circuits where even 0.1pF drift can detune the design.
- Class I C0G/NP0 Dielectric: Offers negligible capacitance change over voltage, temperature, and aging — ideal for frequency-critical applications.
- Compact 0402 Case Size: Supports dense PCB layouts in miniaturized wearables, hearing aids, and sensor nodes without sacrificing performance.
Frequently Asked Questions
- Q: What makes GJM1555C1H5R9WB01D different from a standard 0402 MLCC?
