5.3 B 值越大，残余电阻越小，工作时温升越小。

B The larger the value, the smaller the residual resistance, the smaller the temperature rise during operation. 5.4 热时间常数和耗散系数两者为互为依赖的关系，并不是说某一个数值越大越好或越 小越好，而是两者的乘积越大说明热敏电阻的热容量就越大，那么抗浪涌电流的能力 就越强。 Thermal time constant and dissipation factor as both mutually dependent relationship, not tosay that one or the greater the value, the better the smaller the better, but the product of the two greater the heat capacity of the thermistor greater, then resistance to surge current, the stronger 5.5 热敏电阻用于电源电路时主要是用来抑制开机时的大浪涌电流，大的浪涌电流是电 容放电产生，所以电路中所要安装的滤波储能电容的选配也是很关键的一个条件，为 确保热敏电阻器能够安全的起到保护电路的作用，所以要求电源设计厂家也应该充分 考虑这一因素。 When the power supply circuit for the thermistor is mainly used to suppress largeinrush current at power-on, a large inrush current is the capacitor discharge, the filter to be Rev 2.0 : www.leiditech.com 12.01.2019 9/24 10D-15

installed in the tank circuit capacitance matching is a very critical condition to ensure that the thermistor circuit can play a role in security protection, so the powersupply design requirements for manufacturers should also take full account of this factor. 5.6 通过电路中的最大工作电压和最大启动电流等参数可以利用公式R=U/I 计算出电阻 值范围。 Through the circuit maximum operating voltage and maximum starting current and other parameters can use the formula R = U / I calculated the resistance valuerange. 5.7 以上这些选用原则可以锁定出NTC 热敏电阻的对应型号，如果贵司有特殊设计需要 可与我司技术部洽谈。 These principles may choose to lock the NTC thermistor corresponding model, if your company has special design needs with our technical department to discuss. 6、存储条件 Storage condition 6.1 存贮环境条件 温度 Temperature -10℃～+40℃ 湿度 Humidity ≤70%RH 期限 Term ≤6 months (先进先出 First-in/ First-out) 地点 Place 1.不要暴露在下列环境条件下，否则将导致性能衰退或 参数漂移 Do not exposing the components to the following conditions, otherwise, it may result in deterioration of characteristics 2.腐蚀性或易氧化气体Corrosive gas or deoxidizing gas 3.易燃易爆气体Flammable and explosive gases 4.油、水和化学溶液Oil, water and chemical liquid 5.太阳光下Under the sunlight Rev 2.0 : www.leiditech.com 12.01.2019 10/24 10D-15

12 NTC热敏电阻注意事项NTC thermistor to use matters needing attention

请遵循以下事项，否则可能会造成 NTC热敏电阻损坏，使用设备损伤或引起误动作等后果 Please follow the following, or may result in damage to the NTC thermistor, the use of equipment damage or cause false action, etc. ①、请勿在使用温度范围以外使用，请勿施加超出使用温度范围上下限的急剧温度变化。 Please follow the following, or may result in damage to the NTC thermistor, the use of equipment damage or cause false action, etc. ②、请在额定功率条件下使用 NTC 热敏电阻。各规格最大额定功率为Φ7—1.2W Φ9—1.9W Φ11—2.3W Φ13—3W Φ15—3.5W Φ20—4W Please use the NTC thermistor under the rated power. The maximum rated power of each specification is Phi 7 Phi 9 - 1.2W - 1.9W 11 - 2.3W 13 - Phi Phi Phi Phi 20 3W 15 - 3.5W - 4W ③、在高湿高温环境下使用护套型 NTC 热敏电阻时应采取仅使护套封闭部分暴露于环境（水中 湿 气）中，而护套开口部分不会直接接触到水及蒸汽的设计 In the high humidity and high temperature environment, the sheath type NTC thermal resistance should be used only to expose the sealing part of the sheath to the environment (moisture in water), and the opening part of the sheath will not be directly exposed to the design of water and steam. ④、配线时应确保导线端部（含连接器）不会深入水.蒸汽.电解质液等否则会造成接触不良。 Wiring should ensure that the end of the wire (including connectors) will not be deep water. Steam. Electrolyte solution, etc., will result in poor contact. 剂的场所中使用。 Please do not be exposed to the corrosive gas environment (.NH3.SOx.NOx Cl2) and will be exposed to the electrolyte solution. ⑥、请勿过度拉伸及弯曲导线，请勿施加过度的振动.冲击及压力 Do not over stretch and bend the wire, please do not exert excessive vibration. ⑦、金属腐蚀可能会造成设备功能故障，故在选择材质时应确保金属护套型及螺钉紧固型 NTC 热敏电阻与安装的金属件之间不会产生接触的电位差。 Metal corrosion may cause equipment fault, so make sure not between metal metal support and screw fastening type NTC thermistor and installation of the contact potential difference in the choice of materials. Rev 2.0 : www.leiditech.com 12.01.2019 23/24 10D-15

⑧、功率型 NTC 周围应避免安装发热和易燃元件，建议选用弯脚上部引线较高的产品，使 NTC 热敏电阻在线路板上高出其它元件，以免发热影响其它元件正常工作。 Around the power type NTC should be avoided to install heat and flammable components, recommended products with higher bending the upper lead, the NTC thermistor on the circuit board is higher than other elements, so as not to affect the normal work of other heating element. ⑨、NTC 热敏电阻是按不同的功能用途分别进行设计的,如有疑问可与我司联络。 NTC thermistor is designed according to different functions, such as the question can contact with me.
