Elko-Frage

Beitragvon LX2000-Fan » 11.04.2010, 15:59

Hi
möchte in der nächsten Zeit den Ein-Aus-Taster nachbauen. Nur finde ich bei Pollin keinen Elko mit 1µF und 16 Volt . Es gibt 1µF mit 35V oder 10µF mit 16V. Könnte mir jemand sagen ob ich evtl. einen dieser Elkos verwenden kann und was ich ändern muss??
Danke

Weisst du was die []V bedeuten?
Wenn du einen Kondensator mit Nennspannung 16V auf 32V lädst, dann bricht die Spannung über dem Dielektrikum durch=>KURZSCHLUSS!!
Einfacher gesagt: Du darfst ein Kondensator nur bis an seine maximale Nennspannung aufladen. Würde aber besser paar Volt drunter bleiben um sicher zu gehen.

OK Danke :)

Leider hab ich noch eine Frage:
Es ist ja egal wieviel Spannung (einmal 5V und einmal 8V) man auf die Schaltung gibt man muss nur den Vorwiderstand der LED ändern oder??
