Through Hole Resistors: 55J10RE Application Field and Working Principle

Through hole resistors, also known as axial lead resistors, are composed of cylindrical or rectangle-shaped components with two leads protruding from the sides or ends. They are often used in power supplies, decoders, switches, and other applications requiring an adjustable wire connection. 55J10RE through hole resistors are specifically designed for low-voltage, medium-power resistive applications, capable of handling up to 2A, non-inductive, non-polar. This article will explore the application field and working principle of 55J10RE through hole resistors.

Application field of 55J10RE

55J10RE through hole resistors are commonly used in a variety of applications, including power supplies, decoders, switches, and adjustable wire connections. These resistors are also used as voltage dividers, current limiters, transient voltage and current absorbers, surge protectors, and noise suppressors. They are also often used as temperature sensors, combining with a thermistor or thermocouple for temperature measurement. Moreover, 55J10RE through hole resistors are frequently employed in circuit protection applications like pre-regulators, post-regulators, and soft-start circuits. In addition, the small size makes them suitable for PCBs and other high-density applications.

Working Principle of 55J10RE

55J10RE through hole resistors feature a cylindrical body with two separate leads protruding out of two ends. Inside the resistor is a resistive element, typically constructed from materials such as non-inductive, non-polar metal or ceramics. The resistance value is usually labelled on the resistor’s outer shell. The principle of operation is based on the Ohm’s law formula: R = V/I (Resistance = Voltage/Current). When a current passes through a resistor, it will experience a voltage drop, which is proportional to the current flowing through it. The resistor’s resistance value determines the level of voltage drop.

In addition to the ohmic resistance, 55J10RE through hole resistors may also display a non–ohmic resistance. This is caused by the temperature coefficient of the resistor material, which varies according to the change in temperature. In general, the higher the temperature coefficient, the higher the rate of change in resistance. To ensure proper operation of a component, it is important to choose a temperature coefficient value appropriate for the intended application.

Conclusion

In conclusion, 55J10RE through hole resistors are specially designed for low-voltage, medium-power resistive applications, with an adjustable lead connection. These resistors are commonly used in power supplies, decoders, switches, voltage dividers, temperature sensors, and other applications requiring an adjustable connection and current limiting. The working principle is based on Ohm’s law formula, and temperature coefficient affects the ohmic resistance of the resistor.
