Hi,

Can someone help me identify a through hole transformer from a boost circuit?

It only says L8902A1 B000421 on one side.



Any help or guidance will be appreciated.

Thanks

 

It is almost certainly not an off the shelf transformer so it will be made specially for the manufacturer of the device. It is unlikely that the manufacturer will supply the transformer as a spare for two reasons. 1 It is very unlikely to fail. 2 If it does fail the value of the rest of the board is so small it is cheaper to stock the complete unit as a spare. I can only assume that you want to build a copy of the unit as it is so unlikely that the transformer would be the cause of the unit not working.

Les.
