Through Hole Resistors

Through hole resistors are kind of resistors which are made by inserting through holes in the printed circuit board (PCB). They are most often used for high power applications and can be found in many different forms, shapes and sizes. The most commonly used through hole resistor is the SQZ500JB-9R1.

Application

The SQZ500JB-9R1 through hole resistor is designed for use in high power switch mode power supplies (SMPS) and is also suitable for voltage regulation, power factor correction (PFC) and EMI/RFI noise filtering. It consists of two terminals for connecting to the PCB and is capable of dissipating up to 500W at 25-30°C with an operating temperature range of -25°C to +105°C. It is also suitable for use in photovoltaic solar cells and is RoHS compliant. The SQZ500JB-9R1 is also suitable for use in energy efficient lighting applications, such as LED lights. It is able to handle high currents in a very small form factor and is flexible enough to be used on a variety of different applications.

Working Principle

The basic working principle of a through hole resistor is simple as it has two terminals connected to a PCB. The resistor is capable of limiting the current flow within a circuit. The amount of current passing through the resistor is determined by the resistance value. When a voltage is applied to the resistor, the current will flow through the resistor and it is then divided by the resistance value of the resistor. The voltage across the resistor is then equal to the current times the resistance of the resistor.The SQZ500JB-9R1 through hole resistor is capable of dissipating the energy consumed by the circuit and also helps to prevent damage due to excessive current draw. It also helps to reduce noise and electromagnetic interference in the circuit.

Conclusion

Through hole resistors are a vital component in any circuit design, and the SQZ500JB-9R1 through hole resistor is one of the most commonly used. It is ideal for high power applications and can be found in many different forms, shapes and sizes. The basic working principle of a through hole resistor is simple as is the case for the SQZ500JB-9R1. It is capable of dissipating the energy consumed within the circuit and also helps to reduce noise and electromagnetic interference.
