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

Typical Applications & Why This Part Fits

• RF Impedance Matching Networks: The ±1% tolerance and C0G dielectric ensure minimal capacitance shift over frequency and temperature, critical for 50Ω matching in transceiver front-ends.
• PLL Loop Filters: 17pF with 50V rating suits charge-pump filters requiring tight capacitance stability to maintain phase noise performance.
• High-Frequency Bypass: The 0402 footprint reduces parasitic inductance, while C0G’s low ESR keeps self-resonance high—ideal for decoupling at GHz-range IC supply pins.

Key Features & Advantages

• Tight ±1% Tolerance: Enables precise frequency tuning without post-assembly trimming, reducing calibration costs.
• C0G/NP0 Dielectric: Ultra-stable capacitance (±30ppm/°C) with virtually no aging, ensuring long-term reliability in oscillators and filters.
• Small 0402 Size: Saves board space for dense designs while still delivering 50VDC withstand in RF or mixed-signal modules.

Frequently Asked Questions

1. Q: What makes GJM1555C1H170FB01D different from a standard MLCC?
   A: Unlike X7R or X5R parts, this C0G capacitor offers zero voltage coefficient and extremely low capacitance change over temperature—essential for precision circuits where ±1% tolerance matters.
2. Q: Is GJM1555C1H170FB01D 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 service, including fast prototyping supply.
