Through Hole Resistors are one of the most common electronic components present in a wide range of electrical and electronic devices. They are a type of electrical resistor that is used to reduce the electrical current passing through a circuit. The resistance of a resistor is usually expressed in Ohms (Ω) and can be classified into two broad categories: fixed resistors and variable resistors. This article will explore the application field and working principle of one of the most popular types of through-hole resistors: B20J3K5E.

The B20J3K5E is a 3.5-kiloOhm through-hole resistor with power rating of 1/2 watt. The resistance is marked with the standard IEC colour code on the body of the resistor. And the maximum working digital temperature for the B20J3K5E is +85°C, with a tolerance of 5%. This makes it suitable for use in a wide range of electronic devices and equipment, including amplifiers, vehicles, circuit boards, audio systems, and more.

At the most basic level, these types of resistors work by simply restricting the flow of electrical current through a circuit. When electrical current passes along the resistor, some of the energy of the current is converted into heat. This is known as Ohm\'s law, which states that voltage across a resistor is directly proportional to the current passing through the resistor.

However, traditional resistors are far from perfect when it comes to limiting electrical current. This is where the B20J3K5E steps in. This 3.5 KiloOhm resistor is especially designed to limit the amount of current in a circuit. The resistor is made up of two metal plates that are connected in series, each with a specific resistance value. This makes it very effective at reducing the current passing through a circuit.

Apart from its power-limiting capabilities, the B20J3K5E also features a temperature coefficient of 0.4%/°C, ensuring stability of the resistor’s resistance over varying temperatures. This makes the B20J3K5E suitable for use in high-temperature environments such as cars and industrial equipment.

In addition to this, the B20J3K5E is also perfect for creating various circuit configurations. For example, it can be used to create series and parallel circuits as well as a voltage divider. The voltage divider is made up of two or more resistors that are connected in series and then broken up by a voltage source. This voltage source is then used to reduce the output voltage of the circuit.

Overall, the B20J3K5E is a versatile fixed resistor which can be used in a wide variety of applications. Its wide resistance range and relative stability over varying temperatures makes it a popular choice for electronics professionals. From controlling electrical currents to creating various circuit configurations, the B20J3K5E is an indispensable through-hole resistor.
