PowerLamella Press-fit Powerelements are the pluggable high current contacts from Würth Elektronik ICS. Fully compatible with PowerRadSok pins, they reduce the assembly effort for your service technicians or customers. Whether for board-to-board or – with cable lug – wire-to-board connection: In addition to the socket, you will also find the matching mating contacts.
Depending on the pin configuration and the layout, currents of up to 400 Amps are possible.
Samples are available even in small quantities.

Flexible packaging options: bulk, trays or in blister on reel for cost-effective assembly. In addition, you have the option to package the items in ESD blister tape, optionally with Kapton stickers or completely in your desired packaging.
Massive press-fit technology is the process of pressing solid pins into an electrically plated-through hole in a printed circuit board. Powerelements for press-fit technology have excellent mechanical and electrical properties, making them ideal for use in harsh environments such as high temperature fluctuations or vibration. The press-fit process creates a high performance, gas-tight cold welded connection with a contact resistance of just a few μOhm. This ensures very high current carrying capacity through low resistance contact points.
Printed circuit boards must be designed in accordance with the latest edition of IPC A 600. In the case of solid press-fit technology, the PCBs must be designed in accordance with the Würth Elektronik ICS Press-fit Specification. Special attention should be paid to hole diameter and copper thickness.
The current carrying capacity must always be considered in the context of the overall system. Our measurements have shown that the limiting factor is usually to be found in the PCB layout or in the connection of external leads. (Contact resistance press-in zone 100-200 μΩ). The plug-in elements have a contact resistance of: 0.2 mΩ at Ø 3.6 mm, 0.09 mΩ at Ø 6.0 mm and 0.05 mΩ at Ø 10.0 mm.
