POLYFUSE® Resettable PTCs
Radial Leaded
30R Series
Description
• The 30R series radial leaded device is designed to
provide overcurrent protection for low voltage (≤30V)
applications where space is not a concern and resettable
protection is preferred.
Features
• RoHS compliant and
lead-free
• Fast time-to-trip
• Cured, flame retardant
epoxy polymer insulating
material meets UL 94V-0
requirements

I hold = Hold current: maximum current device will pass without tripping in 23°C still air.
I trip = Trip current: minimum current at which the device will trip in 23°C still air.
R min = Minimum resistance of device in initial (un-soldered) state.
R 1max = Maximum resistance of device at 23°C measured one hour after tripping.
V max = Maximum voltage device can withstand without damage at rated current (Imax
)
Caution: Operation beyond the specified rating may result in damage and possible arcing
and flame.
I max = Maximum fault current device can withstand without damage at rated voltage (Vmax
)
Pd = Power dissipated from device when in the tripped state at 23°C still air.
