Hammond 195J50 10 mH 50 A DC Single Coil Chassis Mount Choke

The 195J50 is a heavy current, chassis mount choke from the 195 Series, a single coil inductor rated 10 mH at 50 A DC. It is built for engineers and integrators designing high current power supply filters, where an open core and coil inductor bolted to a chassis or panel is the practical way to smooth DC output.

The 195J50 is rated 10 mH at 50 A DC with 0.023 ohm resistance. Its drawing is UL listed under file E207860, specifies Class B 130°C operating temperature and carries a caution that the unit weighs 87 lbs.

The ordering table lists dimension A at 9.00 in (229 mm), B at 9.75 in (248 mm), C at 7.50 in (191 mm), D at 7.00 in (178 mm) and E at 6.25 in (159 mm), with mounting slots (G) of 0.44 x 0.75 in (11 x 19 mm). Shipping weight is 79 lbs (35.83 kg), and the series table lists 79 lbs. Inductance is measured at the rated D.C. current, and both inductance and resistance carry a 15% tolerance.

Mounting uses a 4-slot bracket, and connections are made to a screw terminal or heavy copper tabs with holes. The 195 Series is hipot tested at 2,500 VAC with a recommended maximum operating voltage of 600 VAC (winding to core), and is rated for operation from -40C to 85C and storage from -40C to 105C. The chokes are UL approved under Type 3AH, E207860, 30V7, and the 195J50 is listed as RoHS and REACH compliant. Class b insulation is listed in the ordering table.

For AC applications from 60 Hz to 10,000 Hz, the manufacturer points to its 197 Series instead.
