Impedance Behavior

Impedance vs. Frequency (characteristic shape for 68pF NP0/C0G capacitor)

SRF: ~800 MHz Capacitive Inductive Usable range (≤ SRF) 439 mΩ 4.2 Ω 39.3 Ω 371.2 Ω 3.5 kΩ |Z| impedance 1M 3.5M 12.6M 44.7M 158.7M 563.5M 2.0G
Impedance reaches its minimum at the self-resonant frequency (~800 MHz). Below SRF the part behaves as a capacitor; above SRF parasitic inductance dominates. Use at ≤ ⅓ SRF (~267 MHz) for predictable capacitive behavior.
