⑦ 绝缘电阻值 :>1000 MΩ,将热敏电阻的引出端连接起来作为一个电极,金属箔
作为另一个电极,在两电极间施加直流电压 100V±15V 测量两个电极间的绝缘电阻,
施加电压的时间为 1min,绝缘电阻不小于 1000 MΩ;
Insulation resistance: 1000 MΩ ohm, the terminal of the thermistor connected as an
electrode, metal foil as another electrode, 100V ± 15V DC voltage is applied between the
two electrodes measure the insulation resistance between the two electrodes, the voltage
applied to the time of 1min, the insulation resistance of not less than 1000 MΩ;
⑧ 耐电压 :将热敏电阻的引出端连接起来作为一个电极,金属箔作为另一个电极,
在两电极间施加一个频率为 40Hz-60Hz,取规定绝缘电压 1.4 倍的 AC 电压(AC500V)为
峰值电压,持续时间为 60s±5s,电压应近似于 100V∕s 的速率逐步施加,热敏电阻器
应无击穿或飞弧。
High voltage terminal: thermistor connected as an electrode, metal foil as another
electrode in two electrode applied between a frequency of 40Hz-60Hz, AC voltage and
insulation voltage of 1.4 times the provisions (AC500V) for the duration of the peak voltage,
60s + 5S, the rate of voltage should be similar to the 100V / s thermistor applied gradually,
there should be no breakdown or arcing.
⑨ B 值(K)( B Value)
:2800±10%
用以下公式表示指数:Using the following formula
B =【( Ta × Tb )/( Tb – Ta )】 × In( Ra / Rb )
或者
B = 2.303 ×【( Ta × Tb )/( Tb – Ta )】×log( Ra / Rb )
公式中:
B--
常数(单位为 K)Constant (unit K)
Ra--
在温度 Ta(单位为 K)下测定的零功率电阻值(单位为Ω);
Rb--
在温度 Tb(单位为 K)下测定的零功率电阻值(单位为Ω)。
Ta=298.15K
Tb=358.15K
B 值是材料系数或指热敏指数,B 值的大小由材料特性决定,B 值允许±10%公差
范围,影响 B 值大小的因素属材料特性;B 值不同,残余电阻大小不同,持续工作时温
升也不同;B 值越大,残余电阻越小,工作时温升越小。
B value is the material coefficient or thermal index, B value is decided by the size of the
material properties, allowing the + 5% tolerance range of B value, B value influence the
size of the material properties; the B values are different, the residual resistance of
different sizes, continuous working temperature rise is also different; the bigger the B
value, the residual resistance is small when the temperature rise is small.
4、热敏电阻选用原则 Principle of thermal resistor is chosen
4.1 热敏电阻的最大工作电流>回路的工作电流
Thermistor maximum operating current> loop operating current
4.2 热电阻的标称电阻值 R≥1.414*E/Im
Nominal resistance values of thermal resistance R≥1.414 * E / Im
E 为线路电压 E is the line voltage Im 为浪涌电流 Im a surge current 一般来讲
对于开关电源 转换电源 不间断电源 逆变电源等 Im=100 倍工作电流对于灯丝加
热器等的电路 Im=30 倍工作电流
In general, the switching power supply, switching power supplies, uninterruptible
power supplies, power inverter and other times operating current Im = 100For the
filament heater circuit like Im = 30 times the operating current.
4.3 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.
4.4 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
to say 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
4.5 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 large inrush
current at power‐on, a large inrush current is the capacitor discharge, the filter to be
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 power supply design
requirements for manufacturers should also take full account of this factor.
4.6 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 value range.
4.7 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.

9 NTC热敏电阻注意事项 Matters Needing Attention For NTC Thermistors
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
PleasefollowtheruleslistedbelowwhenusingNTCthermistors.Otherwise,youmay
causedamagetotheNTCthermistorandrelevantequipmentorhurtyourself.
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。
Do not use the thermistor under temperature beyond the operating temperature range.
Do not apply rapid temperature changes which exceed the upper and lower limits of the
operating temperature range.
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Φ5-0.7W Φ7—1.2W
Φ9—1.9W Φ11—2.3W Φ13—3W Φ15—3.5W Φ20—4W
Please use the NTC thermistor under the standard power. The maximum standard powers of
each specification are :Φ5-0.7W Φ7—1.2W Φ9—1.9W Φ11—2.3W Φ13—3W Φ15—3.5W
Φ20—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
When using the sheath type NTC thermistors in the high humidity and high temperature
environment, the sealing part of the sheath should be exposed to the environment (moisture
or water) while the opening part of the sheath is not directly exposed to the water or 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。
When wiring, the ends of the wire (including connectors) should not be posited deeply
inside water, steam. electrolyte solution, etc. Otherwise, it 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 expose the thermistor to corrosive gas (NH3, SOx, NOx, Cl2) or any saline
solution, acid solution, alkaline solution and 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 or bend the wire. Please do not apply excessive vibration, pressure
and impact on the thermistor.
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。
To avoid equipment faults caused by metal corrosion, please choose the right material
to make sure there is no potential difference at the contact point between metal sheath type
or screw fastening type NTC thermistor and the metal components.
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。
Do not install any flammable component or component generating heat surrounding the
power type NTC.
Our recommendation is to avoid the negative effect brought by the heat from the NTC,
please use products with higher lead wire on the bending feet to make the NTC thermistor
on the circuit board higher than the other components.
