Würth has unveiled power line chokes that boast a
novel plastic casing, separating strip, and grid plate. The WE-TPB HV Series of
three-phase chokes are targeted at high-voltage applications such as frequency inverters and high-performance charging


insulation materials used in these current-compensated
chokes are UL94-V0 listed.
Furthermore, in order to enhance stability on the PCB, the power line chokes can be fixed in
place with a tapping screw.

The new chokes
guarantee a rated voltage up to 760 Vac, which Würth says is 70% more than
offered by comparable products in the market. Free samples of these power line chokes based on
Würth’s patented design are
available on request.
