## **Notes:** 

- IH : Hold current: maximum current device will pass without interruption in 20°C still air. IT : Trip current: minimum current that will switch the device from low resistance to high resistance in 20°C still air. 

- VMAX Operating : Maximum continuous voltage device can withstand without damage at rated current. This voltage is used for component Recognition under UL1434. 

- VMAX Interrupt : Maximum voltage that can be safely placed across a device in its tripped state. 

- IMAX Interrupt : Maximum fault current device can withstand without damage at rated operating voltage. This current is used for component Recognition under UL1434. Devices may trip safely under higher level power cross conditions to assist equipment in meeting the appropriate ITU, UL60950 or GR1089  industry requirements. 

- PD : Power dissipated from device when in the tripped state in 20°C still air. 

- RMIN : Minimum resistance of device as supplied at 20°C unless otherwise specified. 

- RMAX : Maximum resistance of device as supplied at 20°C unless otherwise specified. 

- R1MAX : Maximum resistance measured one hour post-trip or post-reflow at 20°C. 

- ** Applies to all products which share the same prefix.

## **Solder Reflow** 

- Recommended reflow method: IR, vapor phase oven, hot air oven. 

- Surface-mount devices are not intended to be wave soldered to the  bottom side of the board. 

- Recommended maximum paste thickness of 0.25mm (0.010in). 

- Devices can be cleaned using standard industry methods and solvents. 

## **Rework** 

- If a device is removed from the board, it should be discarded and replaced with a new device.

## **Warning** 

- Users should independently evaluate the suitability of and test each product selected for their own application. 

- Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame. 

- These devices are intended for protection against damage caused by occasional overcurrent or overtemperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated. 

- Contamination of the PPTC material with certain silicone-based oils or some aggressive solvents can adversely impact the performance of the devices. 

- Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and mechanical procedures for electronic components. 

- PPTC devices are not recommended for installation 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. 

- Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above the rated voltage of the device.

However, users should independently evaluate the suitability of and test each product selected for their own applications.
