关于 MS 系列电阻高频下阻值变化研究技术资料 (Study on the Change of Resistance Value under High Frequency of MS Series Resistors TECHNICAL NOTE)
■摘要
●我司 MS 电阻，即合金箔电阻，属于合金电阻系列，在客户端的电路使用中大部分是承担电流检测片的作用，所以耐电流能力是衡量合金箔电阻性能的一大指标，但是作为一个电阻使用，阻值的稳定性和准确性就至关重要，在不同频率的工作环境下，由于合金箔电阻本身电感值的存在，会产生不同大小的感抗，如果是一个高阻电阻，感抗对产品阻值的影响可以忽略不计，但作为一个低阻电阻产品，感抗对测量阻值的影响是显著的，特此针对关于 MS 的高频下阻值变化做以下研究。
■Abstract
●Our MS resistor, also known as metal foil chip resistor, belongs to the metal resistor series and is mostly used as a current detection chip resistor in the circuit at customer end. Therefore, current resistance is a major indicator to measure the performance of metal foil chip resistors. However, as a resistor, the stability and accuracy of the resistance value are crucial. In working environments at different frequencies, due to the presence of the inductance values of the metal foil resistors, different sizes of inductive reactance will be generated. If it is a high resistance resistor, the influence of inductive reactance on the resistance value of the product can be ignored. However, as a low resistance resistor, the influence of inductive reactance on the measured resistance value is significant. Therefore, the following research is conducted on the changes of resistance values of MS resistors at high frequencies.
