Rectangular connector operating environment conditions Rectangular connector ambient temperature: refers to the product in the specified ambient temperature should be used. Even if the outside temperature is not high, if the rectangular connector product works in the chassis, the heat dissipation condition is poor, and other components heat up, the ambient temperature of the product will be much higher than the outside ambient temperature. Use in excess of the specified ambient temperature can also cause damage to the metal coating or insulation. Moisture or water: Moisture or water will form a water film on the surface of the insulator, which will reduce the insulation performance and even cause misleading communication between adjacent contact parts. In general, connectors that are used for long periods of time in high humidity or in the presence of water should be sealed.
