Through Hole Resistors are electronic components that control current flow in a circuit. One of the common types of through hole resistors is the SQBW20330RJ, and this article will explore the application field and working principle of this type of resistor in order to better understand its functions and features.

The SQBW20330RJ is a precision resistor; it has a non-inductive winding technology that allows for consistent performance over its operating range. It is a wire wound precision resistor that is commonly used in electronic circuits to control current flow. It is also known as a ‘power resistor’ due to its thermal shock resistance, high power tolerance, and wide tolerance band. These features make it suitable for use in high power circuits, such as those used in electrical power supplies and motor drive circuits.

In addition, the SQBW20330RJ resistor is also capable of handling high voltage, up to 2.5KV. This makes it suitable for use in high voltage applications, such as AC motors, as it is able to handle large amounts of power without damaging the other components in the circuit. The high voltage capability also makes it suitable for use in applications where protection from voltage surges is required.

The working principle of the SQBW20330RJ resistor is relatively simple. It is made of a metal film wrapped around a ceramic core, which is encased in a plastic shell and held into place by two metal terminals. When the current passes through the resistor, the ceramic core acts as an insulator, preventing the current from passing through the resistor. Thus, the current is controlled by the resistance of the resistor, and the voltage across the resistor is determined by Ohm’s Law.

The SQBW20330RJ resistor is also capable of providing protection from over-current situations. This is due to its high power tolerance, which allows it to absorb large currents without introducing additional distortion into the circuit. Thus, the SQBW20330RJ is an ideal component for use in applications where power consumption needs to be kept low, such as in portable electronics or automotive applications.

Overall, the SQBW20330RJ resistor is a type of precision resistor that can be used in a variety of demanding applications. Its ability to withstand high voltage and to provide protection from over-current situations make it an ideal choice for use in a wide range of electronic circuits. Furthermore, its metal film winding technology ensures consistent performance throughout its operating range, making it an excellent choice for those looking for reliable and durable performance.
