The PWDI13231 is a DC filter choke for the Johnson Invader 2000, listed in the series ordering table as the L301 choke. It comes from the Peter W. Dahl files of transformers and chokes for amateur radio products, and suits restorers and technicians rebuilding the high-voltage supply of an Invader 2000.
The choke is specified as 4-10 HY at 500 mA DC, with the primary rating given in detail as 10 HY at 90 mA to 4 HY at 500 mA DC. That swing in inductance from light to full load is the behaviour of the original L301 filter choke in this transmitter's supply.
It is built on an EI-175 x 2 lamination core in Style 5 of the series style sheet. The ordering table gives an approximate weight of 14 lbs, and the part page lists a shipping weight of 14 lbs (6.35 kg). PWDI13231 is marked REACH compliant and RoHS compliant, with UPC 623980398075 and UNSPSC 39121301.
Dahl-series parts are usually built to order one at a time, and units already built carry Hammond part numbers, as this one does. The series recommends confirming availability by phone or e-mail; stock units can usually be shipped next business day.
