- 1.5H ±15% inductance at rated 300 mA DC current
- 40 ohm ±15% DC resistance; 400 VDC maximum operating voltage
- Open-bracket channel mount, mounting style C12H (A 3.69 in x C 2.31 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 158TA is a 1.5 henry DC filter choke rated for 300 mA DC, pairing more inductance than the 1.0H 158T with the same current rating.
It is the only C12H-frame part in this group, with a 3.69 in (93.7 mm) A dimension and a 1.7 lb catalogue weight, and a DC resistance of 40 ohms.
Electrically, the 158TA is specified at 1.5H ±15% with its inductance measured at the rated 300 mA DC. DC resistance is 40 ohms ±15% and the maximum operating voltage is 400 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 C12H: the series table lists A 3.69 in, B 2.00 in, C 2.31 in and D 3.13 in with a 0.19 in mounting hole. Weight is 1.7 lb in the series table and 1 lbs (0.45 kg) shipping weight. The part is RoHS and REACH compliant (UNSPSC 39121301, UPC 623980207933).
Ideal For
- High voltage power supply filtering
- DC reactor for supply rails up to 400 VDC at 300 mA
- Open-bracket channel mounting in equipment chassis
- Replacement filter choke for existing 158TA designs
