Hammond 196K6 Dual-Coil 12mH 6A / 3mH 12A Chassis Choke

The 196K6 is a dual-coil heavy current chassis mount choke rated 12 mH at 6 A DC in series connection and 3 mH at 12 A DC in parallel connection (short description "PAR 3mH 12ADC SER 12mH 6ADC"). It lets one part serve either a higher-inductance or a higher-current DC filter.

The part page lists 0.056 ohms resistance per winding, while the series table lists 0.052/0.056 ohms. No insulation class is given. The open core and coil assembly uses 4-slot bracket mounting, with overall dimensions of A 3.37 in (86 mm), B 3.06 in (78 mm), C 2.81 in (71 mm), D 2.81 in (71 mm) and E 2.50 in (64 mm), and 0.20 x 0.38 in (5 x 10 mm) mounting slots.

The 196K6 weighs 4.45 lbs (2.02 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.
