Hello, my Cernox is malfunctioning, and I'm trying to figure out what could have caused the problem. I'm seeing a current of 15-20uA at 295K (which is misleading because it's supposed to be 120ohm at 300K for 2mV excitation). But at 78K, it still has a current of 10uA. This happens after I soldered the leads onto PCB pads. I don't think the solder iron was applied for more than a couple of seconds, but it seems the Cernox is malfunctioning since. Are there any failure mode that could cause Cernox to have similar current across temperatures?
Thank you.
Thank you.
