[QUOTE="mich181189, post: 724955, member: 315279"] Hi, I got one of these things of eBay a few months ago, and when plugged in, the current limiting thermistor promptly removed itself from the circuitboard forcefully. After it's been sitting in a cupboard for a while I thought I'd look into getting a replacement. My question is, would a 2.5 ohm 5A one do the trick? I know it should really be somewhere in the region of a 1A one (120 ohm) however rapid have a minimum order of 1000 on the 1A ones! _http://www.rapidonline.com/Electronic-Components/Filters-Suppression/NTC-Inrush-Limiters/NTC-Inrush-limiters/31809/kw/inrush+current+limitor I'm thinking that this should probably do the trick of taking the edge off the inrush. If you think it'd be too much inrush current still, any ideas of where to get a more suitable one? [/QUOTE]
