Hardware Need help replacing charging port

[FAST6191]

Thanks for that.

I am curious what it is.
Measuring at a frequency like that makes it sound like an inductor of sorts. The apparent mass of wound wire when they go pop also attesting to that, not to mention some of those pictures making it look like an air core winding.

I did a search for "Charger Filter Regulator" intending to see about such things and top results were for Nintendo gear, and as such it is a fairly meaningless term. There do appear to be cheap ones online ( https://www.fasttech.com/product/2109600-em10-electromagnetic-charger-filter-regulator-for for a multi pack and http://www.retro-video-game-repair....regulator-for-nintendo-ds-ds-lite-dsi-dsi-xl/ for an individual) but that is online and I am not wondering if we can't just find something in a real world electronics shop, failing that I wonder if it can't just be bridged -- if you just have a fairly well regulated USB port instead and charge via that then the inductor is of limited use.

I found this in an old thread:

"I found someone on a forum identify it - its real name is a 600 MegaOhm Common Choke [the DS Lite's EM10] (- It cost me about $2 for one) . I understand its purpose is to protect the circuitry from variations in the input power supply. Some people just remove it and short the terminals.

Knowing its made made it much easier to find local suppliers. I ordered one from RS Components and 24 hours later (ie now) have installed it. It is charging as I type this. Really pleased with RS's service".

Small m is usually milli, which is 10^-3, and if it was a 600 MegaOhm (mega is 10^6) then at 5V you would only get 0.00000833333333mA passing through it. To charge up a 850mAh battery would then take over 11000 years.

Thanks for the clarification. I suppose that the piece could be 600 milliohms. At least, now we can say that the EM8 is a wire wound SMD common mode choke.

Hey! Have you got a link from RS Components? Also keen to order some EM10. Thanks

Sorry, I don't have a link. I didn't order EM10, I was just quoting someone else.

Okay no problem
