Through hole resistors are used to limit the flow of electricity through an electronic circuit. They are available in various sizes and capacitances, but the most common type is the B8J4K0 size, which is often used for high voltage applications. The B8J4K0 resistor is a three-pin component consisting of a metal-oxide semiconductor, a thermistor and a capacitor. It is widely used for electronics applications such as:

Application Field of B8J4K0 Resistor

• High voltage power supplies
• DC-DC converters
• Motor control systems
• Inductor current limiter applications
• Over-voltage protection circuits
• Interior bus voltage regulators

Working Principle of B8J4K0 Resistor

The working principle of the B8J4K0 resistor is simple. When current passes through the metal-oxide semiconductor, it creates thermal energy, which heats up the thermistor in the middle of the component. This increases the temperature of the resistor and, in turn, increases its resistance. The thermistor is thermally coupled to the capacitor, which absorbs the current, resulting in higher resistance. This allows the B8J4K0 resistor to act as a current limiter in high-voltage circuits.

The B8J4K0 resistor is capable of handling large amounts of current, making it an ideal protection device for circuits with high voltage and high currents. It is also known for its precision and accuracy and is often used to stabilize voltages in power supplies and protect against sudden surges. It can also be used to limit the current drawn by motor control systems, over-voltage protection circuits and interior bus voltage regulators, among other applications.

The B8J4K0 resistor is easy to install and use and can help protect against power surges and voltage drops in a variety of electronic applications.
