The Hammond 193CP is a D.C. filter choke from the 193 Series of enclosed and potted chassis mount chokes, rated 20 henries at 100 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 193CP is the epoxy-potted counterpart of the enclosed 193C: the same 20 henries at 100 mA, but with a 184 ohm resistance and a higher maximum operating voltage of 800 VDC compared with 600 VDC for the enclosed model.
As a potted model, the 193CP is epoxy potted in a black powder paint drawn steel housing and mounts with 1/4"-20 hardware, which is included. It uses the P1 mounting style, with Dimension A 3.31 in, B 3.88 in and C 4.25 in. Like every 193 Series unit it is vacuum impregnated with polyurethane varnish for quiet, long-life operation and has minimum 8 in long leads.
Electrically, the 193CP has a resistance of 184 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 lbs, and the shipping weight is 3.3 lbs (1.50 kg).

Frequently Asked Questions
What are the inductance and current ratings of the 193CP?▾
The 193CP is rated 20H at 100 mA DC, with inductance measured at rated D.C. current and a 15% tolerance on inductance and resistance.
What is the maximum operating voltage of the 193CP?▾
800 VDC maximum operating voltage.
How is the 193CP mounted?▾
It is a potted model in the P1 style and mounts with 1/4"-20 hardware, which is included.
Why does my measured inductance differ from the rating?▾
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.
What temperature and insulation ratings does the 193CP have?▾
Insulation class is 105C and the operating temperature range is -40C to 65C.
Are open bracket-mount versions available?▾
For more sizes and voltages in an open, bracket mount type, the manufacturer points to its 153-159 Series.
