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_dtyp.= 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.

Solder reflow

Caution:

Due to “Lead Free” nature, Temperature and Dwelling time for the

soldering zone is higher than those for Regular. This may cause

damage to other components.

1. Recommended max past thickness > 0.25mm.

2. Devices can be cleaned using standard methods and aqueous

solvent.

1. If reflow temperatures exceed the recommended profile, devices

may not meet the performance requirements.

2. Devices are not designed to be wave soldered to the bottom side

of the board.

3. Rework use standard industry practices.

4. Storage Environment : < 30℃/ 60%RH

Warning

Operation beyond the specified maximum ratings or improper use may result in damage and possible electrical arcing and/or

flame.

PPTC device are intended for occasional over-current protection. Application for repeated over-current condition and/or

prolonged trip are not anticipated.

Avoid contact of PPTC device with chemical solvent. Prolonged contact will damage the device performance.
