'[OT] Part identification'
1999\08\27@074736 by Max Toole

I need to know the identity of a part that I think is a varistor. It is dark red, looks similar to a disc ceramic capacitor and has the markings: H A3 175L10 On the circuit board, it has a reference designator of RV1. Does anyone have an idea who the manufacturer might be and what the device is? I think it is used for surge suppression in the circuit. I really appreciate any help from anyone. Max

It's a Metal Oxide Varistor, manufactured by HARRIS AC working voltage = 175 volts DC working voltage = 225 volts Transient energy = 55 Joules Peak transient current = 4500 Amps Varistor voltage @ 1ma Min=247, Nom = 270, Max = 303 Hope that helps!! Mike Rigby-Jones > {Original Message removed}
