(LF) PowerTwo

Double keeps better

Ideal for high-strengh through-bolt connections and space-saving applications due to double-sided PCB mounting

(LF) PowerTwo Press-fit Powerelements are REACH and RoHS compliant, consist of two Powerelements and are ideal for mounting through a PCB. They provide a permanent, reliable connection without stressing the PCB.

Depending on the pin configuration and the layout, currents of up to 500 Amps are possible.

Note:The push-in element is not intended for contacting components or for current injection

MPFT (Massive Press Fit Technology)

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.

PCB design 

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.

Further information

Torques

Torque values for the various thread dimensions are listed on the Technology section. Different material combinations or thread lengths for bushings are not considered. Depending on the thread length, the bushings can be tightened to higher torques.

Current carrying capacity

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 the PCB layout or the connection of external leads (contact resistance press-in zone 100-200 μΩ).

Qualification

(LF) PowerTwo Press-fit high current contacts have successfully passed vibration test and mechanical shock test according to ISO 16750-3 standard. Vibration test according to ISO 16750-3:2012 4.1.2.7 Random test VII Mechanical shock test according to ISO 16750-3:2012 4.2.3 Severity 2.
