Hammond 156R 1.5H 200mA Filter Choke, 400V DC Channel Mount

Rated 1.5H at 200 ma., the 156R is an open-bracket filter choke (D.C. reactor) in the 153-159 Series for low to medium current circuits. OEM designers, repair technicians and builders of high voltage power supplies use chokes of this type for supply filtering. The 156R is rated 1.5H at 200 ma. with 56 ohms of resistance and a 400 V DC maximum, for supplies drawing more current than the 100 ma. class.

The DC resistance is 56 ohms and the unit is rated for 400 V DC maximum operation, with tolerances of 15% on inductance and resistance. Inductance values are taken at the rated D.C. current and will fall slightly above it and rise below it.

Construction uses an economical open bracket channel mount. Units are vacuum impregnated with polyurethane varnish for quiet operation and long life, every unit is Hipot tested (100%) at 1,500 VAC, and leads are a minimum of 5" long.

Its drawing gives dimensions A 2.81" (71.4 mm), B 1.5" (38.1 mm), C 1.69" (42.9 mm) and D 2.38" (60.5 mm), with a weight of 0.5 lbs / 0.23 kg. The part page lists a shipping weight of 0.5 lbs (0.23 kg), and the 156R is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980202907).
