maximum temperature rise (∆T) of 30 K (Kelvin is used for temperature difference, while Celsius is for absolute temperature). This implies that at its full working current, the connector's internal temperature will not exceed 30 K above the ambient temperature. The combined temperature rise and ambient temperature are further limited by the maximum operating temperature rating, ensuring connector durability when used with the proper de-rating curve (refer to ANE006 for more details on de-rating). However, certain applications, like the short acceleration phase of an electric scooter, the transition phase of an electric transformer, or capacitance discharge in a lighting ballast, demand a high current for only a brief duration. 

This presentation will address a crucial question for designers: 

  • Do we have to oversize the connector working current to accommodate this inrush current, or is it permissible to temporarily exceed the specified working current for short periods? 
  • Detailed insights into the thermal behavior of connectors under dynamic, high-current pulses. 
  • Guidelines and recommendations for optimizing connector selection in applications with transient overload conditions.
