- 300mH ±15% inductance at rated 1 A DC current
- 6 ohm ±15% DC resistance; 500 VDC maximum operating voltage
- Open-bracket channel mount, mounting style C14H (A 4.03 in x C 2.63 in)
- Vacuum impregnated with polyurethane varnish for quiet operation and long life
- Every unit Hipot tested (100%) at 1,500 VAC; leads minimum 5 in long
- RoHS and REACH compliant
The 159ZA is a 300 mH DC filter choke rated for 1 A DC and 500 VDC maximum operating voltage, for DC supplies that need ampere-level current capacity.
Its 6 ohm DC resistance and C14H frame make it the first of the ampere-rated 159Z chokes, with a 2.5 lb catalogue weight.
Electrically, the 159ZA is specified at 300mH ±15% with its inductance measured at the rated 1 A DC. DC resistance is 6 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.
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 2.5 lb in the series table and 2.5 lbs (1.13 kg) shipping weight. The part is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980205304).
Ideal For
- High voltage power supply filtering
- DC reactor for supply rails up to 500 VDC at 1 A
- Open-bracket channel mounting in equipment chassis
- Replacement filter choke for existing 159ZA designs
