2. Hold current at all temperatures specified in the SPEC is the conventional performance of PTC obtained by one time reflow welding. PTC can hold 1 hour under
current conditions at a given temperature. This current is not the condition of long-term charging or discharging current for this type of PTC.
3. The above parameters are concluded from one time of reflow soldering processing the PTC. If there is any further heat generated process like injection or
dispensing at the customer's premise, the aforementioned parameters will decrease at certain degree. Therefore the verification test to be conducted is
6. When mounting or using PTC, all injection molding materials, curing adhesives, UV glue , silica gel and cleaning agents or solvents must be tested in terms of
application parameters e.g. temperature, time, and etc to ensure the consistency between the product and the processing before use.
7. When mounting or using PTC, it is not recommended to use circuit board washer water or other cleaning agent. If cleaning is required, it is necessary to verify
the applicability of various cleaning agents, washboard water and solvents, and confirm that they will not affect the PTC performance. The known chemicals that
impacts PTC include but not limited to ethers, benzene homolog, ketones, lipids and derivates that is of strong solubleness and ruinous. Please place the product
in open environment for at least 24 hours to volatilize solvents residuals.
8. Please do not smash, clamp, pull, dent or twist by tool during assembling process otherwise it might be a cause of the performance degradation.
装配过程中，避免用暴力砸、挤、压、拉、扭、刺等方式½用 PTC 本½，以免引起 PTC 性½衰减。
9. When PTC is welded to the PCM in product application, if injection or gluing is needed, it should be completed in as short a time as possible. If the time slot
between mounting and injection or gluing surpasses 1 month, please keep in airtight environment to avoid long air exposure.
12. In the process of PTC processing, if there is soldering iron welding process, it is suggested that the welding position should be more than 1.5mm away from
PTC, the welding tool temperature should be lower than 350 ℃, and the contact time between soldering iron and solder joint should not exceed 3sec.
13. Low resistance SMD PTC humidity sensitivity grade 2, for sealed packaging. If customers find damaged packaging in stock, they should isolate the product
immediately; if there is surplus material, they need to restore the packaging status , and do sealed storage.
