Through Hole Resistors

With the huge number of resistors available, it is easy to get confused on which to use for which application. One of the most popular types of resistors are through hole resistors. Through hole resistors can be found in almost all electronic devices. In this article, we will be focusing on the ER741K5JT through hole resistor and its application field and working principle.

ER741K5JT

The ER741K5JT, or simply 0.5W type ER, is a through-hole (THT) resistor from the ER4 series. This resistor can take up to 0.5 watts and comes with a tolerance of ±5%. It is a four-terminal resistor, so it is usually used in high-precision, low-power, 4-terminal Kelvin sensing applications. The height of the resistor is 10mm.

This through-hole resistor is made of a ceramic and aluminized ceramic composition. It has a thick film coating with a solderable matte tin finish. It also has a very low thermal coefficient, making it ideal for use in high-temperature applications.

Application Field

The ER741K5JT through hole resistor is ideal for a wide range of applications. It is suitable for use in portable and hand-held applications, as well as automotive electronics, commercial and consumer applications. The low thermal coefficient makes it suitable for high-temperature use. The high precision guarantees precision measurement and control capabilities. This resistor is also ideal for precision analog circuits and audio/video circuitry.

The ER741K5JT is also suitable for use in low-power-, digital-, and high-frequency circuits, as well as power supplies. This resistor can also be used in motor control, ignition control and integrated circuits. In addition, its wide range of temperature ratings makes it suitable for use in low- to medium-power- and high-temperature-requirement applications.

Working Principle

Through hole resistors work by creating an electrical resistance. This electrical resistance causes a voltage drop across the resistor, which reduces the current flowing through the circuit. The size of the voltage drop depends on the amount of current flowing through the circuit, as well as the resistance of the resistor itself.

The resistance of a resistor can be adjusted by changing the size, shape, and material of the resistor. For example, if a resistor is constructed from a larger-diameter wire, it will provide more resistance than a resistor constructed from a narrower wire. In addition, the material used to make the resistor can also affect its resistance. Different materials will produce different amounts of resistance.

The resistance of a resistor can also be changed by adding additional elements such as resistors, capacitors, and inductors. Adding these elements will cause the resistance of the circuit to be increased or decreased, depending on the type of element that is added. This is why resistors are often found in combination with other components in order to make up a complete circuit.

Through hole resistors are designed to be able to handle high currents, and are capable of dissipating heat very quickly. This makes them ideal for use in high-power applications, as well as in precision electronic circuits.

Overall, the ER741K5JT through hole resistor is a versatile component that can be used in a variety of applications. Its thick film coating makes it ideal for use in high temperature environments, and its high precision guarantees precision measurement and control capabilities. It also has a wide range of temperature ratings, making it suitable for use in low- to medium-power- and high-temperature-requirement applications.
