Through Hole Resistors

The SQM300JB-10R is an axial-lead resistors, belonging to the type of through hole resistors. These types of resistors are built with a solid wire lead that is inserted into a hole in the printed circuit board (PCB). This type of construction is suitable for general-purpose and high-power applications. They can be used in a wide variety of industries, including automotive, medical, aerospace and defense, and consumer electronics.

Application Field

The SQM300JB-10R resistors are designed for general-purpose use and high-power applications. They can be used to provide electrical isolation between two components in a circuit. They are also suitable for applications such as voltage dividers, current limiting, and power regulation. These resistors can also be used in high-current applications, such as motor controllers, and are designed to handle higher power and higher voltage than other through-hole resistors.

Working Principle

The working principle of the SQM300JB-10R is relatively simple. The resistor is made up of two metal wires connected by a ceramic substrate. When the current passes through the resistor, a voltage gradient between the two metal wires is generated. This voltage gradient is proportional to the magnitude of the current passing through the resistor. The resistance of the resistor is defined by the length of the resistor, the width of the resistor, and the resistivity of the material used.
