Question:

What kind of electrical component is this?? From a circuit board.?

I have no idea what this component is or where to get one. It's from a sleep comfort bed pump and I need a replacement part. Here's a picture of it and the pump label.

Answer:

Do you see the black bridge marked DF 10S near the fuse, and the VDR marked MOV1 as well? I would suspect either of those to be a POSSIBLE cause of the fuse blowing, because the black bridge can't stand much overvoltage, and the MOV can also go short- circuit because it has done its job, protecting from excess voltages. I say possible, because there could also be a string of other damage. But checking those first would be a start. I think there could also be a PCB track that's been vapourised, leading from the mains to the fuse. The flash seems to be under the board, not under the fuse, and I can't SEE a track there.

I think it is a 1.6 amp fuse. Judging by the black streaks on the board, however, something else went wrong, and blew the fuse with a serious overcurrent. That is to say, just swapping the fuse is likely not to fix the unit; it will probably just blow again. Whatever blew the fuse is probably still wrong, unless you know what that was and have fixed it. You can probably just solder in a fuseholder in its place if you cannot find an exact replacement. One with wires at each end will probably be simplest. I suggest you ask the manufacturer how much for a new board. I am guessing that this is for a vinyl air bed. If so, if the mfgr wants too much for a new board, Coleman makes a very good inflator, included with their airbeds, but I think available separately for $15 or so, and you could probably kluge it into place, though you might need to remote the switch.

It's a 1.6 amp class T fuse. The other markings may be the original manufacturers part number, but I can't read them in your picture. Judging by the charred remains of the fuse plastered all over the board, you had a short circuit straight across the mains supply. Unless you find what caused the short and fix it properly, replacing the fuse on its own is a complete waste of time.

Its a 1.6Amp, T, delay or anti- surge fuse. But if you dont know what it is , how do you know that it needs replacement? Dispite the temptation, do not do a kluge repair. It should only be replaced by exact replacement. As a safety device, you will need to determine why the fuse has blown, if indeed it is! Perhaps the pump got jammed or blocked? Faults on the board or wiring may be reason.

Create a format to your circuit on paper. placed the enter beginning on one fringe of the board and the output on the different area. while utilising the perf board, the connections that practice on the schematic take place at little steel inserts which you get on the comparable place which you get the perf board. Draw a dot the place each and each insert will circulate it somewhat is plenty adequate from the others to permit the climate to be located between the inserts. attempt countless layouts to get something that greater or much less flows from enter to output. in case you're able to desire to make particularly some connections to a minimum of one place you should use greater advantageous than one insert and connect them including cord. The enter connector, output connector, and any controls may be fixed on a the enclosure which will additionally residing house the achieved perf board. on your format enable areas for mounting screws. you are able to mount the board to the enclosure with the help of small self made brackets or tubes with screws by them.
