  • Product introduction
  • Electrical characteristics
  •   V max  = Maximum operating voltage device can withstand without damage at rated current (Imax).

     I max   = Maximum fault current device can withstand without damage at rated voltage (V max).

     I hold   = Hold Current. Maximum current device will not trip in 25°C still air.

     I trip    = Trip Current. Minimum current at which the device will always trip in 25°C still air.

     Pd      = Power dissipation when device is in the tripped state in 25°C still air environment at rated voltage.

     Ri min/max  = Minimum/Maximum device resistance prior to tripping at 25°C.

     R1max  = Maximum device resistance is measured one hour post reflow.

     CAUTION : Operation beyond the specified ratings may result in damage and possible arcing and flame.

     V max  = 元件在額定電流下能承受的最大電壓.

     I max   =元件在額定電壓下能承受的最大電流.

     I hold   = 25℃靜止空氣環境中,產品不動作的最大電流.

     I trip    = 25℃靜止空氣環境中,最小動作電流.
