Hammond 195P8 30mH 8A Single-Coil Chassis Mount DC Choke

The 195P8 is a single-coil heavy current chassis mount choke rated 30 mH at 8 A DC (short description "30mH @ 8ADC"). It fills the gap between the 5 A and 10 A versions of the 30 mH range for designers sizing a DC filter inductor to a specific load current.

The part follows the 195 Series open core and coil construction with 4-slot bracket mounting. Its listed winding resistance is 0.3 ohms; no insulation class is given for this model in the series table. Dimensions are A 4.12 in (105 mm), B 3.75 in (95 mm), C 3.50 in (89 mm), D 3.43 in (87 mm) and E 3.00 in (76 mm), with 0.20 x 0.38 in (5 x 10 mm) mounting slots.

No weight is shown in the series table for the 195P8; the part page lists a shipping weight of 8.4 lbs (3.81 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.
