What is GJM1555C1H1R4WB01D MLCC?
The GJM1555C1H1R4WB01D is a high-frequency SMD capacitor manufactured by Murata. Key specs include 1.4 pF capacitance, 50 V rating, C0G/NP0 dielectric, and a tight ±0.05 pF tolerance in a 0402 package. RoHS compliant, it is designed for precise RF tuning and decoupling in space-constrained circuits.
✔ RoHS Compliant / ✔ 0402 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Matching Networks: The ultra-low ±0.05 pF tolerance and C0G/NP0 stability ensure minimal frequency drift, critical for Bluetooth and Wi-Fi front-end modules.
- High-Speed Data Lines: Its 1.4 pF value provides minimal loading on high-frequency signals while maintaining signal integrity in SerDes or differential pairs.
- Sensor Bias Decoupling: The 50 V rating gives ample headroom for power rail filtering in industrial sensors, supported by the 0402 footprint for compact designs.
Key Features & Advantages
- Ultra-Tight Tolerance: ±0.05 pF enables predictable reactance in sensitive oscillator circuits without post-trimming.
- Temperature Stable (C0G/NP0): Capacitance variation less than ±30 ppm/°C, ensuring reliable performance from -55°C to +125°C.
- Size & Voltage Balance: 0402 case delivers 50 V capability in a 1.0×0.5mm footprint – ideal for miniaturized IoT modules.
