Hammond 157H 10H 50mA Filter Choke, 500V DC Open Bracket

Part 157H is a channel-mounted D.C. reactor with 10H of inductance and a 50 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 157H is rated 10H at 50 ma. with 408 ohms of resistance and a 500 V DC maximum operating voltage; the series table assigns it the C6H frame.

Winding resistance is 408 ohms (+/- 15%) and the maximum operating voltage is 500 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.

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 1 lbs (0.45 kg), and the 157H is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980037493). The part page lists a shipping weight of 1 lbs (0.45 kg); the series table lists a unit weight of 0.5 lbs.
