Hammond 195T5 100mH 5A Single-Coil Heavy Current Choke

The 195T5 is a heavy current chassis mount choke rated 100 mH at 5 A DC and listed in the single-coil 195 Series ordering table. It suits DC power supply filtering where high inductance is required at a 5 A load.

The part page lists 0.64 ohms resistance and Class A insulation. Its drawing specifies lug terminals, exciting current of 92.2 mA to 124.8 mA at 5.0 V, 60 Hz, operating voltage of 750 VAC max. and 600 VDC max., and a primary-to-core hipot of 2000 V, 60 Hz for 1 second. The label marks 100 mH @ 5.0ADC and Made in Canada.

Construction is the series open core and coil with 4-slot bracket mounting. Series table dimensions are A 4.50 in (114 mm), B 5.25 in (133 mm), C 3.75 in (95 mm), D 3.75 in (95 mm) and E 3.50 in (89 mm), with 0.20 x 0.38 in (5 x 10 mm) mounting slots; the drawing gives B as 5.25 in max. Weight is 14 lbs (6.35 kg). Note that the manufacturer part page description refers to parallel and series ratings and the 196 Series, while the series ordering table lists the 195T5 as a 195 Series part.

Across the 195-196 Series, inductance and resistance are held to a 15% tolerance, inductance is measured at rated D.C. current, and connections are made to a screw terminal or heavy copper tabs with holes. The series is rated for operation from -40C to 85C and storage from -40C to 105C, with a recommended maximum operating voltage of 600 VAC winding to core. The chokes are UL approved under Type 3AH, E207860, 30V7, and this part is listed as RoHS and REACH compliant.
