Hammond PWDI13169 8.0 HY 1.5A DC Filter Choke, 4000 WVDC

PWDI13169 is a heavy DC filter choke rated 8.0 HY @ 1.5A DC with a 4000 WVDC working voltage. It is part of Hammond's PWDAHL Series, which lists transformers and chokes directly from the Peter W. Dahl files of magnetics for amateur radio products, and is suited to builders of high-power supplies that need substantial filter inductance at high current.

The 1.5A DC current rating combined with a 4000 WVDC working voltage places this choke at the high-power end of the series, and those two values are the key figures to compare against a supply design.

PWDI13169 is built on an EI core and listed as Style 2 on the series style sheet. The approximate weight is 63 lbs and the shipping weight is 63 lbs (28.58 kg), so plan for suitable lifting, handling and mounting. It is REACH compliant and RoHS compliant.

Hammond notes that PWDAHL units are usually built to order one at a time and advises confirming availability by phone or e-mail. Identifiers are UPC 623980474939 and UNSPSC 39121301.

The ordering table does not tie this choke to a specific radio, so the 8.0 HY, 1.5A DC and 4000 WVDC values are the figures to match against your power supply design.
