M Cap 電容

dpcs

新手問嘢.
請問電容是否只睇 uF 和 voltage, 大過它的數值得用得?
我見M Cap 電容 有好多唔同種類, 是否種種類型都用得(大得過原廠的uF和V就得)?
例如有 M TubeCap, M-Lytic HV .....

there're complicated answers to one little capacitor.
there're many factors to be considered for a specific capacitor in each application.  
there're differences in performance for the same kind of capacitor manufactured/provided by various suppliers.
to read, to try, to compare and to think.... probably the most practical way for u to learn more about it's usage.

to echo ur simple questions:
-- "電容是否只睇 uF 和 voltage" <<  No !
-- "大過它的數值.... 用得唔用得?" << depends !
-- "電容有好多唔同種類, 是否種種類型都用得?"  << certainly "種種都用得" !  if not, why so many suppliers/brands in the market ?

uf 最好吾好相差得太遠。各牌子甚至同一牌子但吾同系列都吾同聲!

我的菲仔9700的電容係2端腳,
但MCap有3端腳, 甚至4端腳(In+, In-, Out+, Out-),
究竟點樣接駁 MCap (3端腳 或 4端腳 ) --->  電容位2端腳 ( + & -）

想問多一條問題的voltage(V)係指 DC 或係 AC?

either DC or AC, as printed.

我見MCap有寫VDC,
但我的9700所有根機的電容有寫VDC or VAC, 只寫V.
i.e. 1500uF 16V  <-- 冇寫係VDC 或 VAC

diagram shown.  
for "V" marked only, it represents  " DC voltage " !  
e.g. 1500uf 16V_d.c., E-cap, -20% +80% (typical) can be used.
