Cautions for SMD PPTC Use
SMD PTC
½用注意事项
1. Operation beyond the rated maximum voltage or current may result in device damage and possible electrical arcing or flame
请在规格书规定的最大电压和最大电流下½用，超出 PTC 最大电压或最大电流规格值的操½，可½会导致 PTC 出现电弧， 阻值升高，甚至烧片。
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.
规格书所规定的各温度下的额定电流均是 PTC 经过一次回流焊接得出的常规性½，PTC ½够在不同温度对应的电流条件下保持 1 小时。该电流并不是该型号
PTC ½够适用的长期充电或放电电流的条件。
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
necessary.
规格书所规定的电阻以及电气特性，均是基于在我司指定测试板经过一次回流焊之后的测试。如果客户有二次回流焊或者注塑点胶等其他热工序，会对上述参数有
定程度的衰减。所以需要验证其适用性。
4. The PTC is thermal sensitive device. It is recommended not to design any heat source devices around it to reduce the outside heat source impact.
PTC 为热敏元件，对环境温度比较敏感，建议在 PTC 周围不要设计热源元件，½量减少外部热源的½响。
5. SMD PTC is designed for SMT processing which applies reflow soldering. Please refer to the recommended solder reflow curve. If the reflow soldering
temperature exceeds the recommended value, the PTC might be damaged. Hand welding PTC is prohibited. Heat gun is not allowed to use during the circuit
board components or terminals rework .
PTC 贴片产品是为 SMT 工艺设计的封装½式，焊接工艺为回流焊。焊接工艺可参考推荐的回流焊曲线。如果回流焊温度超过推荐的值，PTC 将有可½受到损伤。禁止
½用手工焊接 PTC，禁止对线路板其他元件或端子返工时½用热风枪。
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.
PTC 贴装或应用过程中,所½用到的各类注塑料、单组½、双组½固化胶粘剂、硅胶，需要对注塑料胶料等材料牌号以及应用参数（如温度、时间等）进行验证，
以确保产品及工艺的匹配性，确认不会½响 PTC 性½之后方可½用。
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.
PTC 贴装或½用过程中，不建议½用洗板水或其他清洗剂进行清洗。如必须½用，需要验证各类清洗剂、洗板水以及溶剂的适用性，确认不会½响 PTC 性½之后
方可½用。已知对 PTC 有½响的化学药品包括½不仅限于醚类、苯类、酮类以及脂类等较强溶解性、破坏性的有机化合物。清洗后将产品放½于敞开的环境中至
少 24 小时，将残留的溶剂进行充分的挥发。
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.
在产品应用中，PTC 焊接至保护板后，如需注塑或打胶，须在½量短的时间内完成，如贴装与注塑打胶时间间隔超过 1 个月，则需密闭保存，可避免 PTC 长时
间暴露于空气环境中。
10. PTC is resettable protection device which shall not be taken for use as switch. Multiple times tripping shall lower the PTC hold current.
PTC 为自恢复保护元件，½并不½½做开关½用，重复多次的保护会降½ PTC 的维持电流。
11. In charging terminal application, PP type material is recommended to use as inner membrane and TPE and PVC type material is inhibited.
PTC 在充电线端应用中，建议½用 PP 类材料做内膜，禁止½用 TPE 类 与 PVC 类等材料做内膜。
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.
PTC 在加工过程中，如有烙铁焊接工艺，建议焊接½½距离 PTC 1.5mm 以上，焊接工具温度½于 350℃，焊接铁头与焊点的接触时间不超过 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.
½阻 SMD PTC 湿敏等级为 2 级，为密封包装。客户如在库存中发现有包装破损的，立即将产品隔离处理；½用时如有½料，需恢复之前包装状态，做密封保存。
