Hammond 193M 10H 300mA Enclosed DC Filter Choke, 800VDC

The Hammond 193M is a D.C. filter choke from the 193 Series of enclosed and potted chassis mount chokes, rated 10 henries at 300 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 193M handles 10 henries at 300 mA with 63 ohms resistance, in the larger X14 enclosed case. The 193MP is its potted equivalent.

The 193M 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 193M has a resistance of 63 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 10.5 lbs, and the shipping weight is 10.5 lbs (4.76 kg).
