The Hammond 193Q is a D.C. filter choke from the 193 Series of enclosed and potted chassis mount chokes, rated 10 henries at 500 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 193Q is the largest and heaviest choke in the 193 Series: 10 henries at 500 mA in the X16 enclosed case, weighing 21 lbs and rated for a 1000 VDC maximum operating voltage.
The 193Q is an enclosed, 4-hole chassis mount choke using the X16 mounting style: Dimension A 3.75 in, B 5.50 in, C 4.56 in, D 3.00 in and E 4.31 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 193Q has a resistance of 53 ohms and a maximum operating voltage of 1000 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 21 lbs, and the shipping weight is 21 lbs (9.53 kg).
Ideal For
- High voltage power supply filtering
- Tube audio equipment power supplies

Frequently Asked Questions
What are the inductance and current ratings of the 193Q?▾
The 193Q is rated 10H at 500 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 193Q?▾
1000 VDC maximum operating voltage.
How is the 193Q mounted?▾
It is an enclosed, 4-hole chassis mount choke in the X16 mounting style with .203 x .38 in mounting slots.
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 193Q 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.
