Hammond 195Q2 35mH 2A Compact Single-Coil Chassis Choke

The 195Q2 is a compact single-coil chassis mount choke from the heavy current 195 Series, rated 35 mH at 2 A DC (short description "35mH @ 2A DC"). It is a fit for lower-current DC supplies that still call for a bracket-mounted open-frame filter inductor.

It uses open core and coil construction with 4-slot bracket mounting. The listed winding resistance is 0.61 ohms and insulation is Class B. It is among the smallest parts in the series: A 2.63 in (67 mm), B 2.00 in (51 mm), C 2.21 in (56 mm), D 2.19 in (56 mm) and E 1.75 in (44 mm), with mounting slots G of 0.19 x 0.38 in (5 x 10 mm).

The series table shows no weight for this model; the part page shipping weight is 1.55 lbs (0.70 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.
