Electrical Characteristics

= Power dissipated from device when in the tripped state at 20°C still air.

= Trip current: minimum current at which the device will trip in 20°C still air.

= Hold current: maximum current device will pass without tripping in 20°C still air.

= Maximum fault current device can withstand without damage at rated voltage (V

= Maximum voltage device can withstand without damage at rated current (I max)

Description

The 60R Series radial leaded device is designed to provide

overcurrent protection for (≤60V) applications where space

is not a concern and resettable protection

is preferred.

Features

Applications

= Typical resistance of device in initial (un-soldered) state.

lead–free

and peripherals

= Minimum resistance of device in initial (un-soldered) state.

= Maximum resistance of device at 20°C measured one hour after tripping or reﬂow

soldering of 260°C for 20 sec.
