Use standard industry practices, the removal device must be replaced with a fresh one. Thermal Derating Curve Typical Time-To-Trip At 25°C · Use PPTC beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame. · PPTC are intended for protection against occasional over current or over temperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated. · Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and mechanical procedures for electronic components. · Use PPTC with a large inductance in circuit will generate a circuit voltage (L di/dt) above the rated voltage of the PPTC. · Avoid impact PPTC device its thermal expansion like placed under pressure or installed in limited space. · Contamination of the PPTC material with certain silicon based oils or some aggressive solvents can adversely impact the performance of the devices. PPTC SMD can be cleaned by standard methods. · Requests that customers comply with our recommended solder pad layouts and recommended reflow profile. Improper board layouts or reflow profile could negatively impact solderability performance of our devices. 第3页 nSMD 035-33V Alpha-Top (Sea&Land Alliance) Recommended Solder Reflow Conditions 300 Preheating Soldering ‧Recommended reflow methods：IR, vapor phase oven, hot air oven.
