Through Hole Resistors

Through hole resistors are components with two leads that are soldered and secured to circuit boards, providing electrical resistance as part of an electrical circuit. While the technology has been around for decades, electronic components companies are now focusing more on smaller, surface-mount components due to increasing demand for low-profile products. The C71K5JT through hole resistor is one of the latest developments in this field.

C71K5JT Application Field and Working Principle

The C71K5JT through hole resistor is a low-profile or “short” sized device designed to fit most applications with limited vertical space. It is mainly used in power, computer, consumer electronic, and automotive circuit applications. The resistor features high-reliability and low-noise operation in a variety of power output requirements, from 10 to 65 watts. Its temperature coefficient of resistance is only 1/200th of that of leading-edge resistors, making it especially suitable for applications where stable operation is required over extended temperatures.

The C71K5JT is made up of four parts: a back plate, dielectric layer, resistive element, and termination. The back plate serves as the foundation for the resistor, providing mechanical and electrical stability by distributing mechanical loads and thermal gradients evenly across the device. The dielectric layer consists of a thin layer of material that reduces the capacitive coupling between the resistive element and the back plate, minimizing the amount of noise and temperature drift due to voltage variation on the resistive element. The resistive element itself is fabricated from high purity materials such as nickel or palladium, and is designed to have a consistent, stable resistance across the board. Finally, the termination is configured in a two-terminal format with either standard or gold-plated connections, depending on the application.

When in operation, the C71K5JT resistive element is driven by an electric current, either AC or DC. This in turn generates heat, which is dissipated from the electrical device by way of thermal radiation and convection. The back plate helps to spread this heat out evenly across the device to maintain a stable and consistent operating temperature. Additionally, the resistor’s low temperature coefficient ensures that the resistor’s value remains reliable even over extreme temperature ranges.

The C71K5JT through hole resistor is an advanced, reliable, and low-profile device designed for use in a variety of electronic applications. Its precision circuitry ensures that it can deliver stable, consistent performance across a wide range of voltages and temperature ranges. With its reliable performance, low noise, and low profile, the C71K5JT is well suited for power, computer, consumer electronic, and automotive circuit applications.
