Create Free Business AccountThe Hammond 193J is a D.C. filter choke from the 193 Series of enclosed and potted chassis mount chokes, rated 10 henries at 200 mA DC. It is designed for high voltage power supply filtering, and is a natural fit for tube amplifier builders, audio equipment restorers and OEM engineers designing linear DC supplies.
The 193J supplies 10 henries at 200 mA in the enclosed X11 case with an 82 ohm resistance and 800 VDC maximum operating voltage. Its potted twin is the 193JP.
The 193J is an enclosed, 4-hole chassis mount choke using the X11 mounting style: Dimension A 3.13 in, B 3.75 in, C 3.81 in, D 2.50 in and E 2.44 in, with .203 x .38 in mounting slots. The unit is vacuum impregnated with polyurethane varnish for quiet, long-life operation, has minimum 8 in long leads, and its case matches power transformers and tube audio output transformers.
Electrically, the 193J has a resistance of 82 ohms and a maximum operating voltage of 800 VDC. Inductance is measured at rated D.C. current, with a tolerance of 15% on both inductance and resistance; the unit will exhibit less inductance at slightly higher currents and more at lower currents. Insulation class is 105C and the operating temperature range is -40C to 65C. The part is RoHS and REACH compliant.
The series table lists a weight of 5.5 lbs, and the shipping weight is 5.5 lbs (2.49 kg).

The 193J is rated 10H at 200 mA DC, with inductance measured at rated D.C. current and a 15% tolerance on inductance and resistance.
800 VDC maximum operating voltage.
It is an enclosed, 4-hole chassis mount choke in the X11 mounting style with .203 x .38 in mounting slots.
Inductance is specified at rated D.C. current; units exhibit less inductance at slightly higher currents or more at lower currents. The manufacturer notes that proper henry testing requires an LCR meter in junction with a 25A power supply that allows DC bias and a higher applied AC drive voltage.
Insulation class is 105C and the operating temperature range is -40C to 65C.
For more sizes and voltages in an open, bracket mount type, the manufacturer points to its 153-159 Series.
