Rookie here, trying to identify this component from a 1988 Z31 Digital Dash Power Supply. Have been able to identify other things in other PCB's and this one here is stumping me. I'm stuck thinking its a safety capacitor, varistor, or even an off chance its a ntc thermistor. Hard to see in this picture, but it is split open at the top. Searches for these numbers on the web have given me absolutely nothing to work with. Hopefully someone can point me in the right direction. Also included picture of the board it belongs to and circled where its home is supposed to be. Any help/suggestions are totally welcome. Thanks!
