Introducing the KNOWLES / CORNELL DUBILIER CDV18EF820JO3 high-frequency mica capacitor, designed for RF and CATV applications. Engineered for precision and reliability, this capacitor offers stable performance across a wide temperature range and high voltage capabilities.
Product Features
Type: Mica Capacitor (CDV18 series)
Rated Voltage: 1000V DC
Capacitance Range: 1 pF to 5,100 pF
Capacitance Tolerance: ±5% (+Tol)
High Q at UHF/VHF frequencies
Very low dissipation factor: 0.0005 (typical)
Low ESR for cool operation
Shockproof and delamination free construction
Minimal change in capacitance with variations in temperature, voltage, and frequency
This mica capacitor ensures resonance-free performance up to 1 GHz, with flat insertion loss within ±0.1 dB across the frequency range. It features ultra-low ESR, high Q factor, and excellent stability, making it ideal for high-frequency RF and CATV applications.
