**Note:** All temperatures refer to topside of the package, measured on the package body surface. 

## **Solder Reflow** 

- Recommended reflow method: IR, hot air, nitrogen. 

- Recommended maximum paste thickness: 0.25mm (0.010in) 

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

- Experience has shown the optimum conditions for forming acceptable solder fillets occur when a reasonable amount of solder paste is placed underneath each device’s termination.  As such, we request that customers comply with our recommended solder pad layouts. 

- Customer should validate that the solder paste amount and reflow recommendations meet its application. 

- We request that customer board layouts refrain from placing raised features (e.g. vias, nomenclature, traces, etc.) underneath PolySwitch devices. It is possible that raised features could negatively impact solderability performance of our devices. 

## **Rework** 

- Standard industry practices. (Please also avoid direct contact to the 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.
