MLCC GJM1555C1H4R0WB01D

What is GJM1555C1H4R0WB01D MLCC?

The GJM1555C1H4R0WB01D is a high-frequency SMD capacitor manufactured by Murata. Key specs include 4 pF capacitance, 50 V rated voltage, C0G/NP0 dielectric, and a ±0.05 pF tolerance in the 0402 package. RoHS compliant, it is designed for stable, low-loss performance in RF and precision timing circuits.

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

Typical Applications & Why This Part Fits

• RF Matching Networks: The extremely tight ±0.05 pF tolerance minimizes impedance mismatch, ensuring consistent filter and antenna tuning at frequencies up to several GHz.
• Oscillator and PLL Loop Filters: C0G/NP0 dielectric provides near-zero capacitance drift over temperature and voltage, maintaining precise frequency stability in 50 V-rated designs.
• High-Speed Digital Decoupling: 4 pF value acts as a low-inductance bypass for sensitive I/O and PLL pins, with the 0402 footprint enabling dense PCB layout without parasitic overhead.

Key Features & Advantages

• Ultra-Tight Tolerance (±0.05 pF): Enables precise capacitive matching for resonant circuits without manual tuning, reducing production calibration time.
• C0G/NP0 Temperature Stability: Capacitance change ≤ ±30 ppm/°C, ensuring reliable performance across -55°C to +125°C industrial temperature ranges.
• Murata GJM Series Construction: Utilizes proprietary thin-film electrode technology to achieve Q > 1000 at 1 MHz, ideal for low-loss RF paths.

Frequently Asked Questions

1. Q: What makes GJM1555C1H4R0WB01D different from a standard 0402 4pF MLCC?
   A: This Murata GJM series part offers a ±0.05 pF tolerance—significantly tighter than the typical ±0.25 pF—and guarantees C0G/NP0 stability, making it suitable for critical RF and precision applications where standard capacitors would introduce unacceptable drift.
2. Q: Is GJM1555C1H4R0WB01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
3. Q: What is the MOQ? Can we get small batches?
   A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply, so even a few pieces are available.
