Through Hole Resistors

Through hole resistors are fixed sandwiched type resistors consisting of two metal plates with an insulation material between them. The purpose of the resistor is to control the amount of current flowing through a particular electrical circuit. The resistance value of the resistor is determined by the size of the plates, the type of material used, and the gap between the two plates. The specific type of resistor used in a particular application is typically dependent on the desired electronically resistive effect.

H840K2BZA Application Field and Working Principle

The H840K2BZA is a through-hole resistor with a resistance value of 8.4K ohms. It is a carbon-based film fixed type resistor intended for use in controlling the current levels in various electrical and electronic circuits. This particular type of resistor is constructed using two carbon-based resistive films with a ceramic insulation layer sandwiched between them. Its resistance value is determined by the thickness of the resistive film, the type of ceramic used, and the air gap between the two plates. The electrical connection to this resistor is typically made with a twist-in terminal.

Due to its excellent stability under temperature changes, the H840K2BZA is often used in applications that require precise control over current levels. It is particularly suitable for controlling current levels in sensors, actuators, and electronic devices. It is also frequently used for impedance-matching circuits, as it has a lower temperature drift than most other types of resistors. Additionally, this resistor is capable of handling up to 500 volts, making it suitable for applications that involve high-voltage circuitry.

The working principle of the H840K2BZA is straightforward. When current passes through the two carbon-based resistive films, the increasing voltage across the resistance element causes the resistance value to change. This change in resistance value is what is responsible for controlling the current levels in the circuit. By adjusting the voltage across the resistor, it is possible to control the current levels in the circuit. This makes the H840K2BZA an ideal choice for applications requiring precision current control.

In conclusion, the H840K2BZA is a through-hole resistor designed to provide precision control over current levels in various electrical and electronic circuits. It is constructed using two carbon-based resistive films with a ceramic insulation layer sandwiched between them. It has a resistance value of 8.4K ohms and is capable of handling up to 500 volts. Its excellent stability under temperature changes makes it suitable for applications that require precise current control.
