Component ID?

[codan]

Hi,

Can someone identify this component is please, it was on a 6v DC lead acid battery--positive + -- side.

Voltage regulator maybe?

Thank You

Is it some sort of zenner thing

Gday Eric,

Nothing comes up with the part No:

Some kind of over-charge protection?

Thats what we are also searching what part is it ?a zenner? regulator? etc....?

But Google showed me that is a capacitor.

D'oh! I must read threads, not just look at the title and pretty pictures!

Do you know why a capacitor would be used on this

I would suggest a Thermal fuse.

I read that it is a weird poly switch (ptc) that provided some protection and a slow (rise) voltage on to the metal detector.
In line...I understand it prevents an in rush of current that could blow the fets.

it's a thermal switch. i see them often on open-frame switching supplies. they tend to go bad a lot. if it reads open circuit it's bad.

HI
This is a thermal switch. It will open circuit when the temperature rises above the value of the device but will revert back to the closed circuit position when the temperature cools down below this temperature.

I concurr I've seen similar things on ups's, sometimes they are the type that dont reset you have to replace them.

I recognize your avatar cody, off a nixie tube web site...maybe just a coincidence.

Thank you all for taking the time.

Really I appreciate it.

I thought it was a thermal switch, but someone said it possessed magical powers that prevented an inrush of current too. It measured a dead short until I exposed it to a heavy load and read open.

Thank you again. Its part number turns up nothing.
