Hammond PWDI13132 60 HY 150 mA Modulation Reactor Choke

PWDI13132 is a modulation reactor, or choke, rated 60 HY @ 150 mA DC. The part page describes it as a Peter Dahl inductor, and it is part of Hammond's PWDAHL Series of magnetics for amateur radio products taken directly from the Peter W. Dahl files. It suits builders and restorers working on modulated transmitters.

The rating is listed as 60 HY @ 150 mA DC CCS with a 2 KVDC test, which gives a clear basis for matching the choke to an existing modulator design.

PWDI13132 is built on an EI core and listed as Style 4 on the series style sheet. The approximate weight is 10 lbs and the shipping weight is 10 lbs (4.54 kg). It is REACH compliant and RoHS compliant.

Hammond explains that PWDAHL units are usually built to order one at a time and that many designs are decades old, so availability should be confirmed by phone or e-mail. Identifiers are UPC 623980284163 and UNSPSC 39121301.

Unlike the application-specific chokes in the PWDAHL Series, the ordering table does not tie PWDI13132 to a particular radio, so the 60 HY, 150 mA and 2 KVDC figures are the values to match against your design.
