Choke coils (chokes), inductors used to filter current, smooth ripple and limit surges in power supplies, lamps and motor drives.

State inductance, current rating and core type; pack in cartons with leads protected. Transformers and power electronics ship with bushings, radiators and terminals protected, on skids with lifting lugs; state kVA, voltage ratio, cooling class and efficiency level, provide routine and type test reports, and check destination rules such as EU Ecodesign, BIS and safety marks.
