Hammond 193V 0.15H 3A Enclosed DC Filter Choke, 300VDC

The Hammond 193V is a D.C. filter choke from the 193 Series of enclosed and potted chassis mount chokes, rated 0.15 henries at 3000 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 193V has the highest current rating in the 193 Series at 3000 mA (3 A) DC, with 0.15 henry (150 mH) of inductance and a 1 ohm resistance, housed in the X14 enclosed case and rated to 300 VDC.

The 193V is an enclosed, 4-hole chassis mount choke using the X14 mounting style: Dimension A 3.75 in, B 4.50 in, C 4.56 in, D 3.00 in and E 3.31 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 193V has a resistance of 1 ohms and a maximum operating voltage of 300 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 9 lbs, and the shipping weight is 9 lbs (4.08 kg).
