Relay Specialties, Inc. - Hammond Manufacturing - Products - Transformers - Power - Chokes & Reactors

Enclosed, 4-hole mount chokes (some models also available epoxy potted in a black powder paint - drawn steel housing (see chart). Potted models mount with 1/4" - 20 hardware (included).
Tolerance of 15% on both inductance & resistance.
Inductances measured at rated D.C. current.
Minimum 8" long leads.
Units will exhibit less inductance at slightly higher currents or more at lower currents.
Perfect for high voltage power supply filtering, case matches power transformers & tube audio output transformers.
Units are vacuum impregnated with polyurethane varnish for quiet and long life operation.
For more sizes and voltages (open - bracket mount type) - link here to our 153-159 Series.
Operating temperature range is -40C to 65C
Insulation class 105C
Proper Henry testing requires an LCR meter in junction with a 25A power supply that does allow for DC bias as well a higher applied AC drive voltage to meet the test specifications.
