LF PowerPlus 2.0 – Powerelements of the latest generation

With the LF PowerPlus product family, Würth Elektronik offers robust and efficient high-current contacts for PCB contacting in press-fit technology applications. They are ideal for connecting components and cables to the PCB or as fastening elements, especially when high torques are required or little installation space is available.

Lead-free design and high torques

All LF PowerPlus high-current elements consist of a stamped brass base body (CuZn37) and a stainless-steel screw element as bolt or bush. The special design of the base body of the LF PowerPlus elements allows population on both sides in the same position, thus delivering a highly compact design. Important: All Powerelements do not contain any lead and are therefore not subject to any time-limited exemption regulation of the RoHS Directive.

The stainless-steel screw of the LF PowerPlus Powerelements supports a high tightening torque: from 1.8Nm with the smallest thread, M4, up to 42Nm with the largest version, M12. Depending on the layout, the LF PowerPlus high-current contacts can carry currents of up to 400 amperes.

Proven quality and advantages in assembly

• The LF PowerPlus 2.0 series offers the same mechanical and electrical properties as its predecessor, but is substantially simpler to process:The screw tip facilitates simple insertion and positioning of the nut, making automatic screwing effortless
• The pin or nut is now firmly attached to the element, which increases stability and further facilitates automatic screwing
• The pin arrangement (symmetrical instead of asymmetrical) facilitates processing
• An improved pin design reduces the required press-in forces
• Special press-in tools are no longer required

LF PowerPlus 2.0 high-current contacts are available in sizes M5, M6 and M8, each as a socket or pin version. Changing over from the old to the new system is very simple: the elements are compatible with the old generation as regards their drilling pattern and height. LF PowerPlus 1.0 is therefore interchangeable with LF PowerPlus 2.0. Torque and current-carrying capacity also remain the same.

Designed in proven press-fit technology

Designed as press-fit elements, the LF PowerPlus 2.0 power supply elements naturally have all the specific advantages of this technology: the PCBs are not exposed to temperature stress when the components are installed. The press-fit process is simple to integrate into the process chain. The press-fit is mechanically very stable and has an extremely low contact resistance of 100–200 μOhm.
