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 standard values listed here as well as in custom values to meet
your specific requirements.
