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.
