Through Hole Resistors are an essential component in many types of electronic hardware, especially in high-power applications. The SQM500JB-130K is an example of such a resistor, and its applications and working principles are described in this article.

The SQM500JB-130K is a type of surface mount resistor with a high power rating of 500 watts. It is a non-inductive, double-sided, through-hole component, which has a current capacity of over 130A. Due to its high power rating, the resistor can be used in a variety of applications, such as power supplies, switching power supplies, and DC/DC converters, as well as in automotive, telecommunications, and lighting applications.

The resistor is made from a combination of materials including a conductive ceramic dielectric, ceramic substrate, and metal, which are precision-etched to provide precise electrical properties. The resistor is then coated with a protective layer of silicon rubber, which prevents circuit shorts and provides enhanced reliability.

In terms of its working principle, the SQM500JB-130K resistor functions by limiting the current flow in an electronic circuit. When current flows through the resistor, it creates an electromagnetic field, which induces a voltage in the component. This voltage causes a current to flow in the opposite direction and thus reduces the amount of current passing through the resistor and limits the current in the circuit.

The SQM500JB-130K is a particularly suitable resistor for high-power applications because it is a non-inductive resistor. This means that it acts as a linear resistance, meaning that it does not cause an increase the level of inductive reactance in a circuit, and thus minimises the risk of damage to components due to excessive voltage and current.

The SQM500JB-130K is a robust and reliable resistor, which is why it is so often used in high-power applications. Its precise etching, high current capacity, and low inductive reactance help to ensure its performance in a wide range of applications, making it an invaluable component in many electrical and electronic projects.
