1) The D.C.filter chokes are designed and built to meet the US and international safety standards.
2) Enclosed,4-hole mount or welded plate mount chokes(some models also available epoxy potted in a black powder paint - drawn steel housing, see chart).
3) Tolerance of 15% on both inductance & resistance.
4) Inductances measured at rated D.C.current.
5) Minimum 8"long leads.
6) Units will exhibit less inductance at slightly higher currents or more at lower currents.
7) Perfect for high voltage power supply filtering, case matches power transformers & tube audio output transformers.
8) Units are vacuum impregnated with polyurethane varnish for quiet and long life operation.
9) Operating Temperature Range:-40℃ to +70℃.
10) Storage Temperature Range:-55℃ to +130℃.
