SQZ500JB-15R Through Hole Resistors: Application Field and Working PrincipleThrough hole resistors are electrical components that can be used to reduce current in electrical circuits, or to limit voltages. These components are commonly made from a carbon or metal paste deposited onto a ceramic or fiberglass substrate, or from wire enameled with a dielectric material. The SQZ500JB-15R through hole resistor is a widely used type of resistor, and is available in various shapes and sizes. What makes the SQZ500JB-15R through hole resistor unique is its patented design, which features two leads that are parallel to each other, rather than being connected at one end. This design feature allows the resistor to be used in circuits with high thermal conductivity and minimizes the effect of temperature when varying the capacitance of the circuit. However, to take advantage of this design, it is important that the resistors used are properly matched in size and shape. In terms of application field, this type of through hole resistor is most often used in power-supply designs, particularly forprotection circuits. Specifically, it is often used in power inverters, motor drive systems, power supplies, and rectifiers to maintain high-voltage stability, regulate current, and minimize noise generation. Additionally, these resistors are also commonly used in low-voltage low-current applications, such as for audio and video components. Turning to the working principle of SQZ500JB-15R through hole resistors, this type of resistor works by introducing resistance into a circuit, which in turn decreases the flow of electricity or voltage. As a general rule, the resistance of a resistor increases with temperature, so as a circuit heats up, the resistance of the resistor increases and more electricity or voltage is required to pass through in order for the circuit to remain functional. In a circuit, the resistance of a particular resistor is determined by its size, shape and material. The SQZ500JB-15R through hole resistor has a temperature coefficient of +5%, meaning that its resistance increases by 5% for every 10-degree rise in temperature. This feature ensures that this resistor is able to maintain its characteristic resistance even under high temperatures, thus making it an ideal choice for use in power-supply designs.In addition, this type of resistor can also be used for noise reduction. This can be achieved by introducing a resistor into a signal path, as the resistor will reduce the amplitude of unwanted high frequency noise. Moreover, since the SQZ500JB-15R through hole resistor features a low resistance value, it can also be used as a low impedance filtering source, thus reducing the amount of noise on the signal bus.In conclusion, the SQZ500JB-15R through hole resistor is a widely used type of resistor, and is particularly useful in power-supply designs, low-voltage low-current applications, and noise-reduction solutions. The patented design of this resistor features two leads which are parallel to each other and helps regulate current and minimizes noise generation. These characteristics, combined with its temperature coefficient make this type of resistor ideal for regulating high voltages, as well as noise-free operations.
