PowerLamella Pluggable Original POWER ELEMENT Intelligent Systems 400A combinable reliable established easy to maintain system high contact durability PowerLamella Power Elements are the pluggable high current terminal blocks and spacers of Würth Elektronik. PowerLamella is fully compatible with PowerRadsok. Reduce the assembly time of your service engineers or the efforts of your customers. Simply plug-in, no screwing, done! Depending on the layout, currents of up to 400 ampere are possible. Therefore Power Elements perfectly qualify as connecting elements for fuses, switches and cables to the circuit board or as mounting elements. Application Possibilities Board-to-board Wire-to-board Retainers / fastenings, fuses Easy to maintain connections through plugging instead of screwing In combination with or instead of PowerRadsok Processing Würth Elektronik PowerLamella Power Elements are pressed in into the circuit board. Soldering is not necessary. Therefore the PCBs are not exposed to temperature stress. This processing step easily blends in to the processing chain and is highly cost efficient. With the aid of the corresponding Press Fit tools, several Power Elements can be pressed in simultaneously.

Particular attention should be paid to the drill diameter and the copper thickness. Due to the different layer thicknesses of Hot Air Levelling compared to chemical surfaces, the final diameters vary. Würth Elektronik ICS – Press Fit Specification 5.1 Drill Ø 1,6 +/- 0,025 mm Cu-H Cu A End Ø The current carrying capacity of a Press Fit connection needs to be seen in the context of the overall system. The Press Fit zone has a very low electrical contact resistance of 100 – 200 µOhm. The limiting factor therefore usually lies in the circuit board layout or in the connection of a feed line. The plugging elements have an electrical contact resistance of 0.2 mOhm at Ø 3.6 mm, 0.09 mOhm at Ø 6.0 mm and 0.05 mOhm at Ø 10.0 mm.
