HI,
I bought a lot of 1,200 electronic parts and recieved it today, it came with like 10 of these and I dont know what they are,
If you have an idea what this whole blue thing is then let me know...
Thanks
That small chip in the middle is a "Valor, st1501", but I wanted to find out what the whole board was built to do, It does say JPN on it, im assuming that means Japan, but i cant find a manufacturer or model.
Thanks
so i looked up valor on datasheetarchive.com. it came up with tiny transformers with the part number prefix of "ST" (but not a ST1501), so my best guess is this is some kind of part for a DC-DC converter, or a filter of some kind since the lack of active components on the board and just resistors, caps, the transformer and possibly an inductor, my money is on "filter", but there's only a couple of real ways of figuring it out. first would be to draw a schematic of the module, even better would be to find something bigger with this module installed in to, and find out what the surrounding circuits do.
Hard to say, but I also think it is some sort of pulse transformer or an inductor.
A simple test...get yourself a powerful fixed magnet. Place it on top of the "thing". If it has a ferrite core, you will feel a small but noticeable pull.
