Hammond 196Q2 Dual-Coil 40mH 2A / 10mH 4A Chassis Choke

The 196Q2 is a small dual-coil chassis mount choke from the heavy current 196 Series, rated 40 mH at 2 A DC in series connection or 10 mH at 4 A DC in parallel connection. It is suited to low-current DC filtering where the option to wire for inductance or current is useful.

Each winding has a listed resistance of 0.24 ohms; no insulation class is given. The open core and coil design measures A 3.12 in (79 mm), B 2.12 in (54 mm), C 2.75 in (70 mm) and D 2.81 in (71 mm); no E dimension is listed. The mounting slot G dimension is 0.19 in (5 mm).

The 196Q2 weighs 1.85 lbs (0.84 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.
