Old new bee needs help to Identify

[NDtreehugger]

I repair all my stuff but from time to time I need help to Identify radio shack is not the help the used to be.


This comes from a battery charger and blew out the back everything else seems to be ok.

I think it just took too much through it on a startup

Can you help? I need to know it proper name.

Looks like it may be a 2.5 amp, 250 volt fuse.
Strange looking.

Thats what I thought

But a 2.5 fuse no work.

I was thinking there was more to it????

 

[DRC]

it maybe a thermal fuse, looks somewhat like 150C at the bottom with a maximum through current of 2.5A - that is it can be used at upto 2.5A and will open at 150 centigrade to prevent a fire

where was it fitted - physically and electrically ?
was it in proximity to the transformer ?
is it now open circuit ?

 

[NDtreehugger]

Between the black and red leads

Yes it is now open

I thought the chr3 image uploaded would be the thermal fuse

 

[DRC]

i still think its a thermal fuse, there to prevent a fire from an overheating transformer. i've seen similar looking devices, eg

here

probably makes the most sense on the primary side (mains), especially given the 2.5A / 250v rating.

is that other thing (chr3) a diode ?

my information is a best guess, your safety is your own responsibilty

 

[lineup]

my logic, too,
says this is some thermal protection, overload, component
with the temp limit of +150 degrees Celsius

O-Boy,, I do dislike the liability thing,, it really makes life worrisome at times..

I thank you greatly for your assistance

I will try and locate one.
