Pozdrav grupi!

©to konkretno znaèi CTR (current transfer ratio) parametar kod optokoplera??

Naime,mijenjao bi 4N30 sa 4N32 po ostalim karakteristikama mi prolaze a za :

4N30 - CTR = 100% min 4N32 - CTR = 500% min

Dal mi neko mo¾e to zdravo seljaèki objasnit :-) ? Hvala!

To znaci da na svaki mA struje kroz LED ces dobit minimalno 1mA struje kroz kolektor, odnosno 5 mA kod 4N32.
