Re: Conformal Coating
Cameo;
Since the relays are not hermetically sealed, the coating material (silicone) could contaminate on the contacts due to the arcing while contact make or break.
Attached is a technical note for your reference.
Normally, Conformal coating is applied to protect PCBs and related equipment from the environment.
But I could see there is a restriction on Relays on the PCB. Anyone have an answer for Why NO COATING on RELAYs?
Thanks
Hi,
I've measured the case temperature of a DO-201AD package diode at full load current. How can I back calculate the junction temperature of this diode? Diode part number is MUR420. The data available in the datasheet is only Rj-a. I know that, Tj = Ta + Rj-a*Pd, but I want to know how the...
