Typical Applications & Why This Part Fits

• RF Impedance Matching: The 5.7 pF value with ±0.05 pF tolerance provides the ultra-low variance needed to maintain precise impedance in LNA and filter stages at 50 V operation.
• VCO & PLL Loop Filters: C0G/NP0 dielectric ensures negligible capacitance drift over temperature and voltage, preserving phase-locked loop stability in wireless transceivers.
• High-Speed Signal Coupling: The 0402 package minimizes parasitic inductance, while the 50 V rating offers reliable DC blocking in gigabit-rate data links.

Key Features & Advantages

• ±0.05 pF Precision: Delivers the tightest capacitance tolerance among standard MLCCs, reducing tuning effort and component spread in production.
• C0G/NP0 Dielectric: Exhibits near-zero capacitance change across temperature (−55°C to +125°C) and applied voltage, enabling repeatable circuit behavior.
• 50 V Rated Voltage: Offers a generous safety margin above typical 1.8–3.3 V RF rails, enhancing long-term reliability without sacrificing footprint.

Frequently Asked Questions

1. Q: What makes GJM1555C1H5R7WB01D different from a standard 0402 MLCC?
   A: This Murata GJM series part guarantees ±0.05 pF tolerance and C0G/NP0 stability, whereas generic 0402 capacitors often offer only ±0.25 pF or X7R dielectrics with higher drift.
2. Q: Is GJM1555C1H5R7WB01D 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.
