Through Hole Resistors (THRs) are common components used as part of electronic circuits. They provide electrical resistance and consistent performance over a wide temperature range. The CPCC104R700KE66 is a THR specifically designed for advanced temperature performance requirements. This article examines the application field and working principle of the CPCC104R700KE66 THR.

The CPCC104R700KE66 THR is used in applications where temperatures exceed the 100°C – 125°C limits of typical THRs. The resistor features power ratings of up to 1/2 watt and a high temperature stability of +300ppm/°C. The component is designed with a robust construction that allows for superior shock and vibration resistance for use in harsh environments. The CPCC104R700KE66’s low inductance and low thermal delay time also make it suitable for high-speed circuits and applications with high-frequency switching times.

The CPCC104R700KE66 THR has a basic design comprising of a resistor element and two conductive leads. The thin film resistor element is made of aluminium oxide and formed into a zigzag pattern. This pattern helps to increase the resistor’s temperature resistance and reduce power loss. The element is then placed on a ceramic substrate and connected to the leads using thick film technology. The leads are specially designed to float evenly over the substrate, providing superior contact and thermal conduction of the resistive element.

The CPCC104R700KE66’s working principle involves the resistor element converting electrical current to heat by resistance. The temperature stability of the resistor is determined by the thermal resistance of the resistive element and the thermal conductivity of the substrate and leads. As the resistor element heats up, it begins to expand, which results in a shift in the resistor values due to the nonlinearity of the zigzag pattern. The thermal conductivity of the substrate and leads helps to ensure the heat produced by the resistor element is dissipated evenly, resulting in consistent performance over a wide temperature range.

In conclusion, the CPCC104R700KE66 THR is a robust and reliable component designed to deliver superior performance in high temperature applications. The resistor features a zigzag resistor element formed on a ceramic substrate and connected to two highly conductive leads to ensure good thermal conductivity. The CPCC104R700KE66’s nonlinear element and improved thermal conductivity help to provide consistent performance over a wide temperature range. Overall, the CPCC104R700KE66 THR is an excellent choice for applications where high temperature performance is required.
