The 154EA is a D.C. reactor, or filter choke, from the 153-159 Series of low to medium current chokes, rated 15H (+/- 15%) at 20 ma. D.C. current. It is intended for engineers and technicians building or repairing power supplies, and the series is described as perfect for high voltage power supply filtering. The 154EA is the 154-size choke rated for 500 V DC maximum operating voltage on the part page and series table, giving 15H at 20 ma. with 966 ohms of resistance.
Electrically it offers 966 ohms of D.C. resistance with a 15% tolerance on both inductance and resistance, and a 500 V DC maximum operating rating. Because inductance is specified at rated current, the unit shows less inductance at slightly higher currents and more at lower ones.
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 2.06" (52.3 mm), B 1.25" (31.8 mm), C 1.19" (30.2 mm) and D 1.75" (44.5 mm), with a weight of 0.25 lbs / 0.11 kg. The part page lists a shipping weight of 0.25 lbs (0.11 kg), and the 154EA is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980207902). The part page and series table rate this choke at 500 V DC maximum operating voltage; the part drawing lists 300V. Confirm the rating against your design margin before ordering.
