Hammond 195P20 30mH 20A Single-Coil Heavy Current Choke

The 195P20 is the highest-current 30 mH choke in the 195 Series, rated 30 mH at 20 A DC. It is built for high current power supply filtering where both substantial inductance and a 20 A DC load are needed.

The open core and coil design mounts to a chassis through a 4-slot bracket. Listed winding resistance is 0.13 ohms and insulation is Class B. Dimensions from the series ordering table are A 5.25 in (133 mm), B 6.91 in (176 mm), C 4.47 in (114 mm), D 4.38 in (111 mm) and E 5.54 in (141 mm), with mounting slots G of 0.28 x 0.56 in (7 x 14 mm).

The 195P20 weighs 28 lbs (12.70 kg), per both the series table and the part page shipping weight.

Across the 195-196 Series, inductance and resistance are held to a 15% tolerance, inductance is measured at rated D.C. current, and connections are made to a screw terminal or heavy copper tabs with holes. The series is rated for operation from -40C to 85C and storage from -40C to 105C, with a recommended maximum operating voltage of 600 VAC winding to core. Chokes in the series are hipot tested at 2,500 VAC. The chokes are UL approved under Type 3AH, E207860, 30V7, and this part is listed as RoHS and REACH compliant.
