Radial Lead Resettable Polymer PTCs
JK60 Series
Description
JK60 series radial leaded PTCs are designed to provide
over-current protection for low voltage (≤60V) applications
where space is not a concern and resettable protection is
preferred.

I hold= Hold current: maximum current device will pass without tripping in 25°C still air.
I trip= Trip current: minimum current at which the device will trip in 25°C still air.
V max= Maximum voltage device can withstand without damage at rated current (Imax
)
I max= Maximum fault current device can withstand without damage at rated voltage (Vmax
Pdtyp.= Power dissipated from device when in the tripped state at 25°C still air.
R min= Minimum resistance of device in initial (un-soldered) state.
)
R max= Maximum resistance of device in initial (un-soldered) state.
R 1max= Maximum resistance of device at 25°C measured one hour after tripping.
Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
