Hammond 155J 15H 30mA Filter Choke, 400V DC Open Bracket

Part 155J is a channel-mounted D.C. reactor with 15H of inductance and a 30 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. The 155J combines 15H with a 30 ma. rating and 1026 ohms of resistance, rated for 400 V DC maximum operation.

Winding resistance is 1026 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.

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 2.38" (60.5 mm), B 1.38" (35.1 mm), C 1.38" (35.1 mm) and D 2" (50.8 mm), with a weight of 0.3 lbs / 0.14 kg. The part page lists a shipping weight of 0.3 lbs (0.14 kg), and the 155J is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980202105).
