OPEN BRACKET
D.C. FILTER CHOKES
Economical "open bracket" - channel mount.
Tolerance of 15% on both inductance & resistance.
Inductances measured at rated D.C. current.
Minimum 5" long leads.
Units will exhibit less inductance at slightly higher
currents or more at lower currents.
Perfect for high voltage power supply filtering.
