1. Productintroductie van CDRRI-inductor
Productiedetails: CDRRI-inductor is een verbetering ten opzichte van de basisfuncties van I-vormige inductoren. Om de draden, lussen en spoelen te beschermen tegen het externe magnetische veld en om het interferentie-effect van het elektromagnetische veld dat door het circuit op andere componenten wordt gegenereerd, te verzwakken, worden magnetische materialen gebruikt. Een inductantiemodus voor afscherming, waarvan de belangrijkste functie is het verminderen van de interferentie van de inductantie met de buitenwereld.
