Zoom Modem capacitor value needed

Zoom model 3025 Two ceramic caps have exploaded (lightning hit). I can read 221, but can t read the fourth number on either cap, due to that piece is gone. The cap is rated as 1KV. The modem still works, caller ID and still will connect to the internet, but will only connect at 14.4 or less and has a hum on the line. So it s worth replacing the caps. Not ...

Re: bad multilayer ceramic capacitor at 4 Kelvin?

The capacitance of X7Rs I ve fiddled with fall to 110 when cooled to 4.2K. NP0s keep their capcitance better. But of course this depends on the actual chemical composition of the dielectric. I ve been happy with small-value NP0s in a 0402 case, which can also have quite high SRFs. I have no experience on Si caps but would expect ...
