Hammond PWDI13055 Johnson Viking Courier 10 HY HV DC Filter Choke

PWDI13055 is a high-voltage DC filter choke for the Johnson Viking Courier. It comes from the Peter W. Dahl files that make up Hammond's PWDAHL Series of magnetics for amateur radio products and is suited to Courier owners and technicians replacing the original filter choke.

The choke is rated 10 HY @ 0.35A CCS with a 1500 WVDC working voltage, giving a clear basis for comparison against the original part's inductance and current rating.

PWDI13055 is built on an EI-137 x 2" 29G M6X core and listed as Style 5 on the series style sheet. The approximate weight is 8 lbs and the shipping weight is 8 lbs (3.63 kg). It is REACH compliant and RoHS compliant.

Hammond explains that PWDAHL transformers and chokes are usually built to order one at a time, and that many of the designs are decades old, so availability should be confirmed by phone or e-mail. Identifiers are UPC 623980240565 and UNSPSC 39121301.

The ordering table labels the rating as the choke's PR (primary) winding. When requesting PWDI13055, quoting the Viking Courier application alongside the 10 HY and 1500 WVDC values will help confirm the correct part.
