Amveco Datasheets Print E-mail
Feb 16, 2014 at 09:11 PM

Over the last weeks I was pretty much swamped with designing a new multichannel gadget for the company I work for. As everyone involved in R&D knows, most of it is just hours and days of investigation and research. Ideally, most of this is done on real parts, but there is always more than enough details to be derived from the appropriate datasheets of the manufacturer.

While getting your data from datasheets (irony!) can be a very clean and obvious process, there are still lots of companies handing out mediocre documentation at best. Usually our friends from far east occupy the first ten slots in the category "worst datasheet known to mankind", but not this time! A US company made it straight to pole, the name is Amveco and they make some really nice torodial transformers.

Imagine you found the theoretically perfect transformer for your application and now it's time to check its real world performance. Imagine breadboarding the schematic or building it up with loose wires is no alternative, since the noise level you're aiming for just isn't reachable with such construction techniques (I probably will have to use guard tracks on this one ...). So wanted to design a special prototyping PCB, which is also great practice, as a bonus I can also verify all my PCB footprints at one blow. Now this is where datasheets come in handy - determining the correct footprint for your device of desire, as simple as that.

To me it seems some people at Amveco are not really interested in serving their customers by supplying the relevant data about their products. It seems as if I have to order samples (... time!) directly or order a few from digikey (... time!). What I wouldn't even call a decent catalog, is the only technical ressource available on the net and every reseller refers to this as the "official datasheet". To me this document is utter nonsense, I stared at least 30min at their pixeled drawing and I still have no idea how many pins my component has, let alone where these are located. Not good.

I mean, maybe it's just me, but have a look yourself:

I uploaded the image with a very high resolution, so opening it in a new tab will give you a better idea. What a mess, I hate talking to sales.
