You'd use this kind of component to act as a "slow" suppressor, as it stores a voltage for a short while when not in a charged circuit. Kind of like a miniature battery.
Cheers, Shambles, is it the sort of thing that could then supply some functions with accessories feed/permanent live when the ignition is off?
(ie; for the trip computer memory or other data that requires a small voltage to keep it's memory?)
Seems weird as it only has one wire and is connected like a body earth.
Does it have something to do with alternating current?
(ie; stores energy when engine is running, releases energy when ignition is off)
Could it be referred to as an "electronic earth"?
Not very up on my electronics at all, not bad with general basic electrics but this stuff is beyond me for the most part, once I see how it works then it won't be but for the moment I'm still stumped.
