I have not been able to find a better quality transistor for the same price! Very reliable too! 100Electronics knows what they are doing! Jose Price Quality Value Nov 2, 2013 Beefy NPN transistor Title says it all, but to add, for a great price! these get hot, but are sturby enough, so they dont burn with little abuse. Great for high-power stuff. Atte Price Quality Value Jun 21, 2013 These are good – and genuine These are very well known good old transistors at a very nice price. And maybe many of you do not know it, they are also among the most “faked” ones – I ‘ve had such a bad experience in the past. But not the ones from 100Electronics. Like everything else you buy here, they are genuine. Triantaphyllos
