Users should independently evaluate the suitability of and test each product selected for their own application.
This product should not be used in an application where the maximum interrupt voltage or maximum interrupt current can
be exceeded in a fault condition. Operation beyond the maximum ratings or improper use may result in device damage and
possible electrical arcing and flame.
A PTC device is not a fuse - it is a nonlinear thermistor that limits current. Because under a fault condition all PTC devices
go into a high resistance state but not open circuit, hazardous voltage may be present at PTC locations.
The devices are intended for protection against occasional overcurrent or overtemperature fault conditions and should not
be used when repeated fault conditions or prolonged trip events are anticipated.
In most applications, power must be removed and the fault condition cleared in order to reset a PTC device. However, under
certain unusual conditions, a PTC device may automatically reset. Accordingly, PTC devices should not be used in an
application where an automatic reset could create a safety hazard, such as garbage disposals and blenders.
It is the responsibility of the user to determine the need for back up or fail safe protection to prevent damage that may occur
in the event of abnormal function or failure of the PTC device.
Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above the rated voltage of a PTC device.
Devices are not recommended for reflow soldering.
Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic,
thermal, or mechanical procedures for electronic components.
