A250 Series PTC Devices
Description
The JDTFUSE A250 Series is designed to protect against short duration high voltage fault currents (power cross or power induction surge) typically found in telecom applications (250Vrms). The series can be used to help telecom networking equipment meet the protection requirements specified in ITU K.20 and K.21.

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.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).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.
