Pulsed and Ring Tansformer Core

Product features:

Zhili pulsed and ring transformer core which is made by iron-base nanocrystalline alloy 1K107B strips has high Saturation magnetic induction, high magnetic permeability, low coercivity, low loss, low magnetizing current, good temperature stability and corrosion-resisting features.

Product application:

Can be used to replace permalloy and ferrite and applied in:
. Transformer core in DC-DC, AC-DC, DC-AC converters
. Small-module power transformer core
. Single-ended or double-ended pulse transformer core
. Light-fixture power ring transformer core
