Hammond 195K16 15 mH 16 A DC Single Coil Chassis Mount Choke

The 195K16 is a heavy current, chassis mount choke from the 195 Series, a single coil inductor rated 15 mH at 16 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 195K16 is rated 15 mH at 16 A DC with 0.062 ohm resistance; its drawing lists a 6.00 in maximum for dimension B and a 17 lb weight.

The ordering table lists dimension A at 5.25 in (133 mm), B at 6.00 in (152 mm), C at 4.44 in (113 mm), D at 4.38 in (111 mm) and E at 3.63 in (92 mm), with mounting slots (G) of 0.28 x 0.56 in (7 x 14 mm). Shipping weight is 17.15 lbs (7.78 kg), and the series table lists 17 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 195K16 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.
