Through Hole Resistors are widely used for limiting voltage and current, as well as static voltage dropping, transient overvoltage absorbing, and other types of signal conversion in various kinds of electrical systems. One example of such a device is the PGM400KB-3R3, which, as the name suggests, is a through-hole resistor with a power rating of 400 Watts. It operates at a maximum temperature of 105°C and is encased in a metal-oxide film housing that is designed to withstand high temperatures. The PGM400KB-3R3 is a resistive element with three terminals; one of these terminals is usually connected to a source of power, while the other two allow a user to freely adjust the voltage and current. By adjusting the resistance of the element, users can control the amount of current and voltage supplied to a circuit or device. Additionally, due to its high power rating, the PGM400KB-3R3 is suitable for use in high-power equipment such as induction motors.

The working principle of the PGM400KB-3R3 is relatively straightforward; it consists of two resistors, each with its own resistance value, connected in such a way that the total resistance of the device can be adjusted by the user. When power is applied to the terminals of the system, the resistors work together to limit the amount of current flowing through the circuit. The user can adjust the effective resistance of the device by changing the resistance value of one or both of the resistors. As the power rating of the PGM400KB-3R3 is high, it is commonly used in large electrical systems that require a considerable amount of power.

The PGM400KB-3R3 is mainly used in motor control circuits, transformer windings, AC and DC charging circuits, in-circuit test systems, and lighting circuits. In motor control circuits, this device is used to balance the current supplied to the motor in order to maintain optimal performance. Transformer windings usually contain the PGM400KB-3R3 to protect the transformer against short circuiting and overloading. It also prevents the voltage across the transformer from exceeding the upper limit. AC and DC charging circuits are designed to keep the battery level in check, and they typically contain the PGM400KB-3R3 to regulate the current supplied to the battery. In-circuit test systems use the PGM400KB-3R3 for accurate measurements of current and voltage in various electronic devices. Finally, lighting circuits often contain this device to regulate the current supplied to the lighting fixtures in order to maintain their optimal performance.

The PGM400KB-3R3 is a robust device that operates reliably even in harsh environments. It is designed to survive high temperatures and its three-terminal design makes it easy to adjust the resistance of the device. Owing to its excellent performance and features, the PGM400KB-3R3 is widely used in various applications such as motor control circuits, transformer windings, AC and DC charging circuits, in-circuit test systems, and lighting circuits.
