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

Typical Applications & Why This Part Fits

• RF Matching Networks: The tight ±2% tolerance and low inductance C0G dielectric ensure accurate impedance matching in 2.4 GHz and 5 GHz wireless modules.
• Timing & Coupling Circuits: With stable capacitance over temperature (C0G/NP0), this 39pF MLCC maintains consistent performance in oscillator and PLL loop filters.
• High-Frequency Bypass: The miniature 0402 package combined with 50V rating allows dense PCB placement for decoupling near sensitive RF ICs.

Key Features & Advantages

• Precision ±2% Tolerance: Guarantees repeatable circuit behavior, reducing the need for manual tuning in production.
• Class 1 Dielectric (C0G/NP0): Virtually no capacitance change with temperature or voltage, ideal for resonant circuits.
• Murata GJM Series: Designed for high-Q and low ESR, delivering superior signal integrity in microwave designs.

Frequently Asked Questions

1. Q: What makes GJM1555C1H390GB01D different from a standard 0402 39pF?
