The 159ZG is a 15 mH filter choke rated for 4 A DC and 500 VDC maximum operating voltage, for DC supply filtering at multi-ampere currents.
Its drawing (Rev. 1, 11/06/24) records a 5 V, 60 Hz inductance test with 4 A DC bias and a measured DCR of 0.200 ohms, versus 0.25 ohms in the catalogue table.
Electrically, the 159ZG is specified at 15mH ±15% with its inductance measured at the rated 4 A DC. DC resistance is 0.25 ohms ±15% and the maximum operating voltage is 500 VDC. As with every choke in the 153-159 Series, it will show less inductance at slightly higher currents and more inductance at lower currents, so size it to the actual load current.
Construction follows the series' economical open-bracket channel mount, with leads at least 5 in long. Units are vacuum impregnated with polyurethane varnish for quiet operation and long life, and every unit is Hipot tested (100%) at 1,500 VAC. The part drawing adds manufactured using Class B (130°C) materials, black leads, an operating temperature of -40°C to 105°C and storage from -40°C to 85°C.
Mechanically it uses mounting style C14H: the series table lists A 4.03 in, B 2.25 in, C 2.63 in and D 3.56 in with a 0.19 in mounting hole. Weight is 2.75 lb in the series table and 2.8 lbs (1.27 kg) shipping weight. The part is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980205908).
Ideal For
- High voltage power supply filtering
