Through Hole Resistors are widely used in electronics due to their simplistic design. The SQZ15AJB-5R1 is one such resistor. It is a single-centre longitudinal-stack resistor, making it suitable for high power and power dissipation applications due to its size. This resistor has a temperature range of -55°C to +225°C, allowing it to be used in a variety of applications.

The SQZ15AJB-5R1 is constructed of an insulating substrate, then a core of resistor material, and finally a flame-resistant epoxy coating. The resistor material, normally manganese oxide powder or vitreous carbon, is deposited on the substrate using a high-vacuum direct-current sputtering process. The sputtering process is used to ensure a uniform coating of the resistor material and to ensure that the resistor meets the specified resistance values. This ensures consistent results and performance.

The SQZ15AJB-5R1 is designed to handle up to a peak power load of 3500 watts. The resistance value range for this resistor is from 5 ohms to 15 ohms, with an operating temperature range of -55°C to +225°C. The rated dissipation factor (Df) for this resistor is 0.3w/°C, meaning that it can dissipate three watts of power for every degree Celsius of temperature change. This ensures that the resistor will not overheat or become damaged due to high temperature levels.

The SQZ15AJB-5R1 is suitable for use in high-power and power dissipation applications, such as those in the automotive industry, railway industry, aircraft industry, industrial automation, and telecommunication industries. Its high power tolerance and low Df make it ideal for these types of applications where power is a major factor. The high temperature range also ensures that the performance of the resistor is not affected by the environment that it is utilised in.

In terms of its working principle, the SQZ15AJB-5R1 passes a current through the resistor material and generates a voltage drop across the resistance element. As the current passes through the resistor, heat is generated. This heat must be dissipated away from the device in order to maintain the specified resistance level. This is done by utilizing a metal heat sink or a fan. The heat sink or fan helps to keep the device cool and ensures that the resistance level stays consistent.

The SQZ15AJB-5R1 is the perfect choice for applications which require a high power tolerance and a low temperature coefficient. The device is quick and easy to install and requires minimal maintenance once installed. This makes it the ideal solution for applications which require a simple yet effective resistor.
