Hammond 193Q 10H 500mA Enclosed DC Filter Choke, 1000VDC

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).
