Through Hole Resistors

A H84K12BCA resistor is an electronic component used to produce electrical resistance in a circuit. It consists of a ceramic body with 12 through-hole leads or pins. The main purpose of this resistor is to reduce the current flow and/or voltage drops in a circuit, thereby protecting other components from damage due to excessive current. The resistor comes with pre-wired leads which provide easy installation.The primary application field of the H84K12BCA resistor is for power conversion and control systems. It is mainly used as a dummy load in power supplies and circuits to limit the current or voltage and ensure a safe operating range. The resistor can also be used to create a voltage divider circuit. By connecting a H84K12BCA resistor in series with other components, it will divide the circuit’s voltage, and can be used to control speed or power of a motor, for example.The working principle of the H84K12BCA resistor is based on Ohm\'s law. In a circuit, Ohm\'s law states that the current (I) flowing through the resistor is equal to the voltage (V) across the resistor divided by its resistance (R). Thus, in a H84K12BCA resistor, the resistance is fixed and can be taken as a constant (R = 12 ohms). So, by increasing or decreasing the voltage (V) across the resistor, the current (I) passing through it will be altered accordingly to meet the requests of the circuit.The H84K12BCA resistor is principally composed of a ceramic body and two pairs of metal contacts. The ceramic body is composed of a sintering material, such as porcelain, and is typically strained or pressed to ensure a uniform electrical path. The metal contacts are embedded on both ends of the ceramic body and joined together via a soldering process to create the resistor. The contacts are also typically treated with an anti-corrosive and/or anti-stain material, such as plating, in order to protect it from environmental factors, such as toxins, dust, and moisture. This ensures that the resistor does not lose its electrical characteristics over time.In addition, the H84K12BCA resistor exhibits excellent thermal stability. As its temperature changes, the overall resistance value does not significantly change. This ensures that the resistor remains at a consistent temperature, and that its electrical properties are not affected by the environment. This makes it suitable for use in high temperature and harsh environment electronic applications.Overall, the H84K12BCA resistor is a high performance component designed for applications requiring power conversion and control. Its ceramic structure is highly resistant to environmental factors, and its internal design allows for superior thermal stability and current regulation. It is therefore highly suitable for a wide range of industrial, automotive, and consumer applications.
