PowerOne SMD SMD Technology Original POWERELEMENT Intelligent Systems 300A Inline Processing reliable established configurable SMD Technology PowerOne SMD high current terminals are the direct consequence of advancing our products in the customer’s interest. The Power Elements are processable in the common SMT lines and are soldered in the infrared oven or with the vapor-phase system. Depending on the layout, currents of up to 300 ampere are possible. That is the reason why Power Elements perfectly qualify as connecting elements for fuses and cables to the circuit board or as mounting element. Technical Data Current carrying capacity at 85 °C Material Surface see table on the back CuZn39Pb3 tin-plated (standard) Dimensions Application Possibilities Board-to-board Wire-to-board screw connection of ring terminals Retainers /fastening fuses For mounting Length x width Height from 9 x 9 mm from 7,5 mm Würth Elektronik Test Arrangement – Soldering Profile Tp Tp Critical Zone TL to Tp Ramp-up Würth Elektronik PowerPlus SMD Power Elements are soldered onto the circuit board which easily fits in to the processing chain of an SMT line. Due to the heat absorption of the component mass, individual tests are necessary for defining the parameters.

Footprint indications are available. IPC A 600 Acceptability of Printed Boards IPC TM 650 Torques The torques indicated in the table are based on DIN 267 part 25 and on IPC TM 650 regarding the adhesive strength of copper foil on FR4. Different material combinations or different thread lengths of the connectors are not regarded here. Current Carrying Capacity The current carrying capacity of a Press Fit connection needs to be seen in the context of the overall system. Our measurements have shown that the limiting factor usually lies in the PCB layout or in the connection of feed lines.
