你也太狠了吧,这是一个很大的系统工程啊,靠网络是无法搞掂滴,简单地看一下编码规则也是无法搞掂滴,乱抄别人的东西是要告你侵权滴。我的一个朋友曾经在公司里搞过这个工程,那时曾连续1个月每天晚上在我家恶补相关资料,但拿去公司应用又不是那么回事。我说我利用业余时间为他们公司有偿服务,他们老板又舍不得钱。2个月后我的朋友被FIRE了。
下面给你一个范例供参考,请原谅我不能给你整套文件(事关公司财产)。
3.7.2 Capacitor 6 2 d1 d2 d3 % - w1 w2 w3 t1 t2
d1 d2 d3 : capacitance
d1 = 1st significant digit
d2 = 2nd significant digit
d3 = multiplier in pF
= A ? 10-1 x pF
% : tolerance of equal to or better than specified
= F ? +/- 1%
= G ? +/- 2%
= H ? +/- 3%
= J ? +/- 5%
= K? +/- 10%
= M? +/- 20%
= P ? +100/-0%
= Z ? +80/-20%
w1 w2 w3 : voltage rating in volt for capacitance < 47µF
or voltage rating in volt for capacitance = 47µF
