Through hole resistors, such as the MBA02040C6493FCT00, are resistors that use a physical hole punched or drilled through a substrate material to anchor a metalized patch. The patch is then held in place with a wire-wound resistor or an electrically insulating substance. The resistance of the resistor is determined by the size, shape, and type of substrate material used, as well as the metalized patch used.

In general, through hole resistors are used to reduce current flow, regulate voltage or divide voltage signals. When used to reduce current flow, through hole resistors act as current limiting devices and provide protection against electrical overloads. They also reduce the impact of electric noise that can interfere with the operation of sensitive circuit components. When used to regulate voltage, through hole resistors lower the voltage of a circuit to a desired level by increasing the resistance of the current through it. Similarly, when used to divide voltage signals, through hole resistors are used to reduce the amplitude of the signal and distribute it evenly across multiple voltage nodes.

The MBA02040C6493FCT00 resistors are made with a ceramic substrate material and are specially designed for high temperature operation. The ceramic substrate is engineered to withstand ambient temperatures up to 400°C with minimal or no decrease in its electrical characteristics. The resistors also feature a metalized patch made of a nickel/silver alloy which is engineered to provide stability and superior resistance to mechanical shock.

In terms of application, the MBA02040C6493FCT00 resistors are used in power converters, motor control circuits, and industrial process control systems. Due to their small size and high-temperature capability, they can be used in a variety of constrained spaces where proper heat dissipation would be difficult for larger resistors. Furthermore, since they use a ceramic substrate, they are also well-suited for applications that require a low thermal coefficient.

The working principle of through hole resistors is quite simple. As discussed above, when current passes through the resistor, a voltage drop is caused by the resistance inherent in the device. This voltage drop is proportional to the amount of current flowing through the resistor and inversely proportional to the resistance of the resistor. To quantify this relationship, Ohm’s law states that the current flowing through a resistor is equal to the voltage across the resistor divided by the resistance of the resistor.

Given the rise in demand for power electronics, through hole resistors such as the MBA02040C6493FCT00 are becoming more and more important. By limiting current, regulating voltage and dividing voltage signals, through hole resistors provide critical protection to sensitive electronic components and offer improved efficiency for power converters, motor control circuits, and industrial process control systems.
