Through Hole Resistors

Through hole resistors are electrical components which act as a resistance to electrical current passing through them. They are most commonly used in the field of electronics, electrical engineering and power management. The various types and styles of through hole resistors include axial lead resistors, metal oxide resistors, and film resistors. The SQM500JB-0R39 through hole resistor is a type of axial lead resistor. It is a low profile resistive product which is engineered with a 0.8 mm high body. It is a RoHS compliant resistor featured with excellent moisture and humidity resistance, a wide temperature range and excellent EMI/RFI suppression capabilities.

Application field of SQM500JB-0R39

The SQM500JB-0R39 through hole resistor is a versatile and widely used resistive device. It is suitable for all kinds of electronic applications, such as: coupling, damping, instrumentation amplifier, charge equalization, and static stabilization. It is also ideal for EMI/RFI suppression in LED lighting applications, home appliance, automotive, aviation, aerospace, and military applications.

Working Principle of SQM500JB-0R39

The SQM500JB-0R39 through hole resistor works by providing resistance to an electrical current. It does this not by blocking current flow, but instead, it obstructs the current’s speed and strength by having the electrons continually bumping into a barrier. The magnitude of the resistance is determined by the size of the barrier placed within the resistor. The type of resistor and its resistance value are determined by the amount of material used and the number of turns of wire in the resistor respectively. As the current meets a resistance, the resulting potential energy is dissipated as heat generated in the resistor. An increase in the resistance will cause the current to flow more slowly and thus reduce the power consumed by the circuit.

Conclusion

The SQM500JB-0R39 through hole resistor is an essential component for various electronics applications, from EMI/RFI suppression to charge equalization. It is a low profile product which provides excellent moisture resistance, wide temperature range and an effective current flow to the circuit, as well as heat dissipation. Knowing the application fields and its working principle is essential to understanding how to use the SQM500JB-0R39 properly.
