Part 156C is a channel-mounted D.C. reactor with 150H of inductance and a 8 ma. D.C. current rating. It belongs to the 153-159 Series of low to medium current filter chokes, which the manufacturer positions for high voltage power supply filtering. At 150H, the 156C has the highest inductance listed in the 153-159 series table, rated for an 8 ma. load with 3700 ohms of resistance and a 400 V DC maximum.
Winding resistance is 3700 ohms (+/- 15%) and the maximum operating voltage is 400 V DC. Inductance is measured at the rated D.C. current; expect less inductance at slightly higher currents and more at lower currents, so size the choke to your actual load current.
The choke is built on an open bracket channel frame and vacuum impregnated with polyurethane varnish for quiet, long-life operation. Each unit is 100% Hipot tested at 1,500 VAC and supplied with leads at least 5" long.
The series table lists the C6H mounting style at A 2.81", B 1.50", C 1.69" and D 2.38" with a 0.19" mounting hole, and a unit weight of 0.5 lbs. The part page lists a shipping weight of 0.5 lbs (0.23 kg), and the 156C is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980202402).
