- 1.5mH inductance (+/- 15%) at 5A rated D.C. current
- 0.07 ohm D.C. resistance (+/- 15%)
- 400 V DC maximum operating voltage
- Economical open bracket channel mount, C6H mounting style
- Every unit Hipot tested (100%) at 1,500 VAC
- Vacuum impregnated with polyurethane varnish for quiet operation and long life
- Minimum 5" long leads
- RoHS and REACH compliant
Rated 1.5mH at 5A, the 156B 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 156B is a 5 A DC reactor: 1.5mH with only 0.07 ohms of winding resistance, rated to 400 V DC, on the C6H frame.
The DC resistance is 0.07 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 156B is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980202204).
