CD18FD102JO3F is a high-frequency mica capacitor designed for CATV and RF applications, featuring a capacitance of 1020 pF and a voltage rating of 1000V. This Type CD18 capacitor delivers controlled, resonance-free performance through 1 GHz with insertion loss typically flat within ±0.1 dB over the entire frequency range. The device exhibits near-zero capacitance change with temperature, voltage, and frequency variations, combined with very high Q at UHF/VHF frequencies and a typical dissipation factor of 0.0005. With ultra-low ESR for cool operation and 100,000 V/µs dV/dt capability minimum, this capacitor is ideal for precision RF circuits, signal conditioning, and impedance matching applications requiring stable performance and minimal signal loss.
