xperience 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.

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.
