Time 25 ℃ to Peak Temperature : Note 1: All temperatures refer to of the package, measured on the package body surface. NOTE : Specification subject to change without notice. C Nominal 3.50 Solder reflow ※ Due to “Lead Free” nature, Temperature and Dwelling time for the soldering zone is higher than those for Regular. This may cause damage to other components. 1. Recommended max past thickness > 0.25mm. 2. Devices can be cleaned using standard methods and aqueous solvent. 3. Rework use standard industry practices. 4. Storage Envorinment : < 30℃ / 60%RH Caution: 1. If reflow temperatures exceed the recommended profile, devices may not meet the performance requirements. 2. Devices are not designed to be wave soldered to the bottom side of the board. Reflow Profile Warning: -Operation beyond the specified maximum ratings or improper use may result in damage and possible electrical arcing and/or flame. -PPTC device are intended for occasional overcurrent protection. Application for repeated overcurrent condition and/or prolonged trip are not anticipated. -Avoid contact of PPTC device with chemical solvent. Prolonged contact will damage the device performance.
