Filter Chokes 193 Series Enclosed & Potted Chassis Mount Features 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 85C 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.
