Typical Applications & Why This Part Fits

• RF Impedance Matching: The ultra-low 0.4pF value and ±0.05pF tight tolerance enable precise tuning of antenna matching networks at high frequencies.
• High-Voltage Coupling: With a 200V rating and NP0 (C0G) stability, this capacitor provides reliable DC blocking in power amplifier or high-voltage bias tee circuits.
• Temperature-Sensitive Oscillators: The NP0 dielectric ensures negligible capacitance change across temperature, preserving oscillator accuracy in VCO or TCXO modules.

Key Features & Advantages

• Ultra-Low Capacitance: The 0.4pF rating is ideal for parasitic compensation and high-frequency trimming without adding excessive loading.
• High Voltage in Small Package: 200V withstand in a 0402 size saves board space while meeting demanding isolation requirements.
• Strict Tolerance: ±0.05pF tolerance guarantees repeatable performance in batch production, reducing the need for tuning adjustments.
