Hammond 195S4 70mH 4A Single-Coil Chassis Mount Choke

The 195S4 is a single-coil heavy current chassis mount choke rated 70 mH at 4 A DC (short description "70mH @ 4ADC"). It is suited to DC supply filtering where high inductance is needed at a 4 A load.

It is built with open core and coil construction and 4-slot bracket mounting. Listed winding resistance is 0.6 ohms, lower than the 0.9 ohms of the 2 A 195S2; the series table gives no insulation class for this part. Dimensions are A 3.75 in (95 mm), B 3.25 in (83 mm), C 3.13 in (80 mm), D 3.13 in (80 mm) and E 2.50 in (64 mm), with 0.20 x 0.38 in (5 x 10 mm) mounting slots.

No weight is given in the series table; the part page shipping weight is 5.8 lbs (2.63 kg).

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.
