    WE are Pushing the Power for You

    Power can be different things: people can be powerful but so can electrical components. In the electronics industry, power means the interaction of energy, voltage, current, heat development and resistance. It is about the power supply, the selection of the components to transfer power to the circuit board. It is about components, needed to balance, regulate, store, filter or smooth this transferred power. However, it includes even more than all this. Thermal aspects also need to be considered when dealing with power. Higher currents lead to heat generation, which has to be considered in the selection of electronic or electromechanical parts. That is why we have efficient, powerful and robust products that transmit current with minimal self-heating and low contact resistance.

    WE have the right product for every application. Discover the variety of our huge power product portfolio now.
