Hammond 193B 12H 100mA Enclosed DC Filter Choke, 600VDC

The Hammond 193B is a D.C. filter choke from the 193 Series of enclosed and potted chassis mount chokes, rated 12 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 193B provides 12 henries at 100 mA in the compact X6 enclosed case, one of the smallest housings in the 193 range.

The 193B is an enclosed, 4-hole chassis mount choke using the X6 mounting style: Dimension A 2.50 in, B 2.75 in, C 3.06 in, D 2.00 in and E 1.69 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 193B has a resistance of 155 ohms and a maximum operating voltage of 600 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 2.5 lbs, and the shipping weight is 2.5 lbs (1.13 kg).
