fuse questions

[triplefour]

i have a blown fuse here from a phillips tv a client brought in to fix. its the cylindrical, ceramic type...the smaller one u see in atx power supplies a lot.

it has a little logo on it that looks like LF but the F is inside the L
and then it says right after the logo:
T8AH250VP

i know that this is an 8 amp, 250 volt fuse based on the markings.

but what does the lf mean? is it just a logo?
what does the H mean
and what does the P mean?

and how do i know if this is a slow blow or fast blow? are all ceramics slow blow?
are there different grades of "slow" and "fast" ?

just some general fuse questions.

cant figure out how to word this stuff right to get a good answer on the google, figured someone in here knows better

please, and thank you!

Re: fuse questions

ok thanks... but what is the H and the P for? i found another fuse to replace it with but it doesnt have the P at the end. just wondering what that meant... also the H

Re: fuse questions

Little spec sheet does not give the details on the numbering code as printed on the fuse.
P is more likely for LEAD free.
H is for high interrupt breaking capacity, hence CERAMIC body.
Did you verify that it is 5x20mm dimension?

Re: fuse questions

yea thats what it is. so probably the replacement fuse is fine... but something else went wrong. im going to start a thread for this phillips tv now since replacing the fuse didnt solve it..and the setup in this tv is really strange
