Uses,.light dimmer chokes.60HZ differential-mode Emi line chokes.DC chokes less than 50KHZ or low Et/N.Power factor correction chokes  less than 50KHZ.Resonent Inductors more than or equal to 50KHZ

-8 material with low core loss under high DC bias.and  with good linearity,is a good choice for high frenquency.the price is comparativelyhigher.

Tempreature EffectThe cores will be suited for operation from -55°C-125°C,It has a high curie temperatur and will be function to several hundred degree celsius,However,long time continued high tempreature operate may result in a permanent decrease in inductance and increase in core loss.

Finisih coatingThe core coated with epoxy and have a minimum dielectric strength of 1000 Volt Dc min.
