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.
