CD17ED470JO3F is a high-frequency mica capacitor designed for CATV and RF applications, featuring a capacitance value of 470 pF and a voltage rating of 500 V. This Type CD17 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, combined with very high Q at UHF/VHF frequencies and a typical dissipation factor of 0.0005. With an ultra-low ESR for cool operation and 100,000 V/µs dV/dt capability, this capacitor is ideal for precision RF tuning, impedance matching, and signal conditioning in communication systems and test equipment where stability and low loss are critical.
