Intelligent sensing requires a highly precise and stable operation system, it means the resistance drift under long time operation and noise level of the resistor must be very low.

Yageo thin film chip resistor RT series is a perfect fit for this application. The advanced sputtering technology forms a fine nichrome resistive layer which is able to avoid noise generation. Compared to the thick film resistor, RT series is a better solution because of its narrower tolerance, much lower TCR, and better long term stability (Figure 1, Figure 2).

In addition, because of the inherent differences between the compositions of thin film and thick film resistive layers, the current noise of thin film resistors is also lower than thick film resistors. Low noise feature of RT series reduces the signal sensing error, which is ideal for the application in intelligent sensing or high quality audio systems.
