PRF18BC471RS5RB传感器变送器的温度传感器-PTC热敏电阻规格书PDF中文资料

PRF18BC471RS5RB属于传感器变送器的温度传感器-PTC热敏电阻。由村田制作所制造生产的PRF18BC471RS5RB温度传感器 - PTC 热敏电阻正温度系数 (PTC) 热敏电阻温度传感器是随着温度升高而呈现出电阻增加的器件。与许多其他温度传感器类型相比，热敏电阻产生的输出信号相对较大且易于测量，但它们往往具有不稳定且不适合精确温度测量的特征。PTC 热敏电阻尤其适合于过热检测应用，并且通常表现出明显的非线性温度-电阻关系，因此可用于检测不精确的“高”温条件，但不适于进行精确测量。

1. Sensing accuracy +/-3 deg.C which is highest of PTC

Thermistor and the same level as NTC at sensing point.

2. Same resistance - temperature characteristics as PRF18_QS

series. Easy to use higher accurate sensing type.

3. SMD type is helpful for miniaturizing circuits because of its small

size and light weight.

4. Excellent thermal response due to small size

5. Solid - state construction provides excellent mechanical

vibration and impact resistance.

6. Contactless operation provides noiseless operation.

7. Lead is not contained in the terminations.

8. UL/cULcertified product. (UL1434, File No. E137188)
