Welke ferriet kraal heb je dan gebruikt?
Voor welke frequentie"
Allereerst, wat is de frequentie van het "inpratende" signaal?
Zoek daar dan 1 of meer kernen bij voor die dempende frequentie.
Zómaar een kraal toepassen lijkt mij weinig zinvol.
Ik heb een flink aantal kernen liggen, maar elk met zijn/haar
eigen frequentie toepassing.
Bovendien zijn er twee typen "kernen", Ferriet en ijzerpoeder.
Alle twee voor verschillende toepassingen.
Zowel voor LF inspraak als HF inspraak.
En om z.g. mantelstromen te dempen.
Om een goede keuze te maken lees de documentatie op de Amidon website.
https://amidon.de/contents/de/d541.html
Daar heb ik altijd mijn kernen vandaan gehaald.
Lees ook het hoofdstuk
https://www.jendela.nl/diversen/PADAT137_final_D.pdf
op mijn website waarin e.e.a. wordt uitgelegd.
Dus?
