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.

⑤、请勿在腐蚀性气体的环境（Cl2 .NH3 .SOx.NOx）以及会接触到电解质液.盐水.酸.碱.有机溶剂的场所中使用。

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.

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.
