• 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

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

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.
