ZR41809TC is an epoxy coated toroidal core in Magnetics R material

Magnetics R material is a medium frequency multi-purpose ferrite material. Used in power transformer, inductor and filter designs. Engineered for lowest losses at 95°C.

Ferrite toroids offer high magnetic efficiency as there is no air gap, and the cross sectional area is uniform.

Epoxy is coated to 200C continuous operation. Coating thisckness with Epoxy is typically less than with Nylon
