Hammond PWDI13158 Collins 75A Series L30 5 Henry Filter Choke

PWDI13158 is filter choke #2, position L30, for the Collins 75A-1, 75A-2, 75A-3 and 75A-4 receivers, cross-referenced to Collins P/N 668-0019-00. It is a Peter W. Dahl design in Hammond's PWDAHL Series of magnetics for amateur radio products and suits owners and technicians restoring these receivers.

The choke is rated 5 henry at 80 mA DC with a 600V working voltage. Its companion in the same receivers, filter choke #1 at L29, is listed separately as PWDI13161.

PWDI13158 is built on an EI core and listed as Style 3 on the series style sheet. The approximate weight is 2 lbs and the shipping weight is 2 lbs (0.91 kg). It is REACH compliant and RoHS compliant.

PWDAHL Series parts are usually built to order one at a time, and Hammond advises confirming availability by phone or e-mail. Identifiers are UPC 623980474793 and UNSPSC 39121301.

Because the 75A receivers use two different filter chokes, check the position on the chassis before ordering: L30 takes this 5 henry, 80 mA choke, while L29 takes the 3 henry, 120 mA PWDI13161. Quoting Collins P/N 668-0019-00 with the Hammond number helps confirm the match.
