PTC Devices

Overcurrent Protection Device

Warning: Application Limitations for the LVR Product Line

1. Users should independently evaluate the suitability of and test each product selected for

their own application.

2. 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.

3. A PPTC device is not a fuse - it is a nonlinear thermistor that limits current. Under a fault

condition all PPTC devices go into a high resistance state but do not open circuit, so

hazardous voltage may be present at PPTC locations.

4. 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.

5. In most applications, power must be removed and the fault condition cleared in order to

reset a PPTC device; however, under certain unusual conditions, a PPTC device may

automatically reset. PPTC devices should not be used in an application where an

automatic reset could create a safety hazard, such as garbage disposals and blenders.

Appropriate qualification testing should be performed.

6. 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.

7. Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above

the rated voltage of a PPTC device. This product should not be used in an application

where

the maximum interrupt voltage or maximum interrupt current can be exceeded by

inductive spikes.

8. Devices are not recommended for reflow soldering.

9. Device performance can be impacted negatively if devices are handled in a manner

inconsistent with recommended electronic, thermal, or mechanical procedures for

electronic components.

10. PTC devices are not recommended to be installed in applications where the device is

constrained such that its PTC properties are inhibited, for example in rigid potting

materials

or in rigid housings, which lack adequate clearance to accommodate device expansion.

11. Contamination of the PTC material with certain silicone-based oils or some aggressive

solvents can adversely impact the performance of the devices.
