- 0.9H inductance (+/- 15%) at 75 ma. rated D.C. current
- 125 ohm D.C. resistance (+/- 15%)
- 300 V DC maximum operating voltage
- Economical open bracket channel mount, C1H 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
Part 153L is a channel-mounted D.C. reactor with 0.9H of inductance and a 75 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. With 0.9H at 75 ma. and only 125 ohms of winding resistance, the 153L trades inductance for current and lower DC resistance while keeping the same small C1H footprint and 0.1 lb weight.
Winding resistance is 125 ohms (+/- 15%) and the maximum operating voltage is 300 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 1.63" (41.4 mm), B 0.88" (22.4 mm), C 0.81" (20.6 mm) and D 1.38" (35.1 mm), with a weight of 0.1 lbs / 0.05 kg. The part page lists a shipping weight of 0.1 lbs (0.05 kg), and the 153L is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980200606).
Ideal For
