Introduction to Through Hole Resistors

A Resistance of an electronic component is the force a device has in opposing current or the natural flow of electrons that pass through them. This resistance is typically measured in Ohms, and the material which the resistor is composed of, and its overall dimensions, determine the amount of resistance the device has. Through hole resistors are designed to provide a specified amount of resistance in a simple, standardised form factor that can be easily assembled using a through-hole mounting or soldering process.

SQP40AJB-82R: Application field and Working Principle

The SQP40AJB-82R is an axial leaded through hole resistor, which is used in a variety of areas ranging from fuse circuits, protection circuits, snubber circuits, over-voltage and over-current applications. It is particularly well-suited for use in products such as computers, phone systems, modems, and printers, as it has a large surface area and superior radiation resistance. The power rating of the SQP40AJB-82R is 1/4 watt and it has a ±20% tolerance on resistance. It features a non-inductive windings, an operating temperature of -55°C to +155°C, and an insulation class of UL 94V-0. The working principle behind the SQP40AJB-82R is simple. It consists of a metal wire wound around an insulating material, such as ceramic. When current passes through the device, electrical energy is converted into heat due to the resistance of the material. The heat is then dissipated from the device, as the size of the resistor controls how much heat can be generated. It should be noted that because of its relatively large size, the SQP40AJB-82R is less suited for use in high-frequency applications. However, due to its low thermal resistance and high breakdown voltage, it is suitable for low-frequency circuits.

Conclusion

The SQP40AJB-82R is a through hole resistor, which is designed to provide a specified amount of resistance in a simple, standardised form factor. It is well-suited for use in products such as computers, phone systems, modems and printers, as it has a large surface area and superior radiation resistance. The working principle behind the SQP40AJB-82R is simple, as electrical energy is converted into heat due to the resistance of the material, which is then dissipated from the device. Hence, it can be concluded that the SQP40AJB-82R is an efficient and suitable device for applications requiring a low-frequency resistor.
