Hammond 196G12 Dual-Coil 4.8mH 12A / 1.2mH 24A DC Choke

The 196G12 is a dual-coil heavy current chassis mount choke offering 4.8 mH at 12 A DC in series connection, or 1.2 mH at 24 A DC in parallel connection. It suits power supply designers who want a single stocked part that can cover two current levels.

Each winding has a listed resistance of 0.024 ohms, and no insulation class is given in the series table. The part uses the open core and coil construction of the series with 4-slot bracket mounting. Overall dimensions are A 3.38 in (86 mm), B 3.56 in (90 mm), C 2.81 in (71 mm), D 2.81 in (71 mm) and E 3.00 in (76 mm), with mounting slots G of 0.20 x 0.38 in (5 x 10 mm).

The 196G12 weighs 6 lbs (2.72 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.
