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
• Cured, flame retardant
epoxy polymer insulating
material meets UL 94V-0
requirements
• Fast time–to-trip
• RoHS compliant, Lead-
Free and Halogen-Free*
Applications
• USB hubs, ports
and peripherals
• Computers & peripherals
• Motor protection
• General electronics
• Automotive applications

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.
V _max = Maximum voltage device can withstand without damage at rated current (I_max)
I _max = Maximum fault current device can withstand without damage at rated voltage (V_max)
P_d = Power dissipated from device when in the tripped state at 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.
Caution: Operation beyond the specified rating may result in damage and possible arcing
and flame.
* Effective January 1, 2010, all 30R PTC products will be manufactured Halogen Free (HF). Existing Non-Halogen Free 30R PTC products may continue to be sold, until supplies are depleted.
