Hammond 195D50 1.4 mH 50 A DC Single Coil Chassis Mount Choke

The 195D50 is a heavy current, chassis mount choke from the 195 Series, a single coil inductor rated 1.4 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 195D50 provides 1.4 mH at 50 A DC with 0.005 ohm resistance. Its drawing shows a 5.50 in maximum for dimension B, operating voltage limits of 750 VAC and 600 VDC, and marking as made in Canada.

The ordering table lists dimension A at 6.38 in (162 mm), B at 5.50 in (140 mm), C at 5.38 in (137 mm), D at 5.25 in (133 mm) and E at 3.88 in (99 mm), with mounting slots (G) of 0.28 x 0.56 in (7 x 14 mm). Shipping weight is 28 lbs (12.70 kg), and the series table lists 28 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 195D50 is listed as RoHS and REACH compliant.

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