1^F推rogerable:泥竟然敢用色碼電感來兜power(抱頭)08/30 16:44

2^F→rogerable:買那種長得像甜甜圈的的電感吧還有你電流要多少...08/30 16:45

6^F推rogerable:甜甜圈會發出聲音喔O.O 我暫時是沒遇過哩懇請樓上分享08/30 17:09

11^F→rogerable:頻率跑掉 (還有充電器有不是黑心國的嗎orz)08/30 17:41

13^F推rogerable:Rsc最大跨壓約0.3V 所以最少Ipk*0.3, Ipk跟用法有關08/30 20:31

14^F→rogerable:詳細可以看ST的34063 datasheet後面有列表08/30 20:31

1^F推rogerable:只要流過的電流夠大就會死人08/24 13:48

2^F→rogerable:http://en.wikipedia.org/wiki/Electric_shock08/24 13:48

3^F→rogerable:你可以點中文的條目還算詳細08/24 13:49

4^F→rogerable:基本上"電死人"是一件複雜的事情電壓頻率不同都有差異08/24 13:50

[問題] 為什麼analog/RF IC paper 沒有 device size?
