Hammond 195B150 0.5 mH 150 A DC Single Coil Chassis Mount Choke

The 195B150 is a heavy current, chassis mount choke from the 195 Series, a single coil inductor rated 0.5 mH at 150 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 195B150 carries the highest current of the two 0.5 mH parts in the 195 Series table at 150 A DC, with a 0.0018 ohm winding resistance and Class B insulation, in a 5.25 in (133 mm) by 5.50 in (140 mm) A/B envelope.

The ordering table lists dimension A at 5.25 in (133 mm), B at 5.50 in (140 mm), C at 4.47 in (114 mm), D at 4.38 in (111 mm) and E at 4.13 in (105 mm), with mounting slots (G) of 0.28 x 0.56 in (7 x 14 mm). Shipping weight is 26 lbs (11.79 kg), and the series table lists 26 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 195B150 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.
