Hammond 195T1 100mH 1A Single-Coil Chassis Mount Choke

The 195T1 is a single-coil chassis mount choke from the heavy current 195 Series, rated 100 mH at 1 A DC (short description "100mH @1ADC"). It provides the series' highest inductance value at its lowest listed current, for low-current DC filtering.

The part uses open core and coil construction with 4-slot bracket mounting. Its listed winding resistance is 1.5 ohms, and no insulation class is shown in the series table. Dimensions are A 3.00 in (76 mm), B 2.50 in (64 mm), C 2.50 in (64 mm), D 2.50 in (64 mm) and E 2.00 in (51 mm), with 0.20 x 0.38 in (5 x 10 mm) mounting slots.

The series table lists no weight; the part page shipping weight is 2.3 lbs (1.04 kg). Higher-current 100 mH options in the series are the 195T5 and 195T10.

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.
