Typical Applications & Why This Part Fits

• RF Tuning & Impedance Matching: With ±0.05pF tolerance and C0G/NP0 stability, this 0.85PF capacitor enables precise resonance tuning in filters and antennas without drift over temperature.
• High-Frequency Oscillator Circuits: The 50V rating combined with ultra-low capacitance (0.85PF) minimizes parasitic effects, making it ideal for Colpitts and Pierce oscillator feedback paths.
• Sensor Interface Compensation: Its 0402 footprint suits space-constrained designs, while the C0G/NP0 characteristic ensures predictable capacitance across -55°C to +125°C for sensor signal conditioning.

Key Features & Advantages

• Ultra-Tight ±0.05pF Tolerance: Enables high-accuracy impedance matching and frequency control without post-tuning adjustments.
• C0G/NP0 Temperature Stability: Capacitance change is less than ±30ppm/°C, ensuring consistent performance in thermally varying environments.
• Compact 0402 Package: Saves PCB space while providing 50V breakdown margin, suitable for dense RF modules and IoT devices.

Frequently Asked Questions

1. Q: What makes GJM1555C1HR85WB01D different from a standard 0402 capacitor?
   A: This Murata GJM series part offers ±0.05pF tolerance and C0G/NP0 dielectric, whereas standard parts typically have looser ±0.1pF or ±0.25pF and may use X7R which varies with voltage and temperature.
2. Q: Is GJM1555C1HR85WB01D 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 fast BOM kitting support at SZYY, including quick-turn prototyping quantities for this 0.85PF value.
