It has been said that CASE (Connected, Autonomous, Subscription/Shared, Electrification) is a once-in-a-century technological innovation in the automotive industry. And, while the amount of electricity used by automobiles has increased with the electrification of vehicles, power electronic devices, such as inverters and DC-DC converters, must be made even more compact. In response to the size-reduction requirements, I-PEX released the AP-10 high-power supply terminal in 2020, followed by the AP-LT10 and AP-TSS10, and is again expanding the AP series. The new AP-50 significantly expands the rated operating temperature and rated current values. By using AP-50, the number of connectors required to supply the increased power needed can be reduced. It also contributes to system size reduction as less board space is occupied by connectors.
