Axial Lead Chokes – 90 Series
This series was discontinued on
December 31, 2006. An RoHS-compliant
version will not be made.
Coilcraft’s axial lead chokes are totally encapsulated in a
durable epoxy coating. Their low cost compared to molded
type chokes makes them particularly attractive to high
volume users. Coilcraft chokes are available in the stan-
dard values listed here as well as in custom values to meet
your specific requirements.
