Document 115-1 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.
