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

Typical Applications & Why This Part Fits

• RF Matching Networks: The tight ±0.1pF tolerance and NP0 dielectric ensure minimal capacitance drift over temperature, critical for precise impedance matching in wireless modules.
• High-Voltage DC-DC Converters: With a 200V rating in a compact 0402 body, this capacitor suits snubber or filter circuits where space is constrained yet voltage stress is high.
• Test & Measurement Equipment: The 3.9pF value combined with Murata’s high-Q NP0 construction provides low loss and stable performance for calibration and signal conditioning stages.

Key Features & Advantages

• Ultra-Stable NP0 Dielectric: Capacitance change is virtually flat across temperature ranges, ensuring consistent circuit behavior in harsh environments.
• High Voltage Rating: 200V capability in a 0402 case enables miniaturization without sacrificing breakdown margin for power-related designs.
• Stringent Tolerance: ±0.1pF accuracy eliminates the need for manual tuning in sensitive RF paths, reducing production calibration steps.

Frequently Asked Questions
