What is GJM1555C1H4R4WB01D MLCC?

The GJM1555C1H4R4WB01D is an SMD capacitor manufactured by Murata. Key specs include 4.4pF capacitance, 50V voltage rating, C0G/NP0 dielectric, and an ultra-tight ±0.05pF tolerance. 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 Impedance Matching: The 4.4pF value with C0G/NP0 provides minimal capacitance variation over temperature and voltage, ensuring consistent matching in antennas or filters.
• High-Precision Oscillators: ±0.05pF tolerance guarantees tight frequency control in crystal or MEMS oscillator feedback loops, reducing frequency drift.
• Sensor Interface Filtering: 50V rating withstands transient spikes in industrial sensor lines, while the 0402 package saves space on dense PCBs.

Key Features & Advantages

• Ultra-Low Tolerance: ±0.05pF enables repeatable circuit performance without manual tuning, ideal for production-level RF designs.
• Stable Dielectric (C0G/NP0): Virtually zero capacitance shift with temperature (0±30ppm/°C) and voltage, maintaining accuracy across operating conditions.
• Compact 0402 Footprint: Saves board space while delivering 50V rating, balancing miniaturization and reliability.

Frequently Asked Questions

1. Q: What makes GJM1555C1H4R4WB01D different from a standard 0402 MLCC?
