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 (I_max

)

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 (V_max

)

P_d= Power dissipated from device when in the tripped state at 23°C still air.
