23J2K7E

Through Hole Resistors are one of the most common and important components in electronic circuits. They are used to control the current passing through the circuit and are for applications such as protection from static electricity, thermal control, and pulse production. The 23J2K7E is an example of a through-hole resistor. Below, the application field and working principle of the 23J2K7E will be discussed.

Application Field

The 23J2K7E through-hole resistor is particularly useful for low-voltage power distribution applications. It is recommended for use in high-density circuit boards that are commonly found in medical equipment, communications systems, and aerospace machinery. It is specifically designed for capacitor-input, voltage-controlled current regulation. The resistor can also be used in mobile phones due to its small size and light-weight design.

Working Principle

The 23J2K7E operates by passing a fixed resistor in series with a variable resistor. The variable resistor is then connected into a linear feedback circuit which responds to the input voltage. When the input voltage is below the reference voltage, the output of the circuit is direct current. However, when the voltage reaches the reference voltage, the output switches to a constant current. This current can be manually adjusted by varying the resistance. The amount of resistance contributed by the fixed resistor is determined by the size and type of the resistor.

The 23J2K7E resistor also contains an overload protection circuit which helps protect the resistor from short circuits. The circuit shuts off the power whenever the current exceeds the resistor\'s allowable limit. This prevents the resistor from overheating and ensures its safe and reliable operation. The circuit also has a fault detection circuit that trips when an overload is detected.

In addition, the 23J2K7E has a temperature compensation circuit that monitors the temperature of the resistor and adjusts the response time accordingly. This helps to ensure the stability of the resistor over a wide temperature range. The resistor also has an anti-interference circuit which reduces the level of electromagnetic interference.

Overall, the 23J2K7E through-hole resistor is an important and versatile component that is useful for a variety of applications. Its small size and light-weight design makes it suitable for use in high-density circuit boards, and its various safety features help protect the resistor from damage due to overloads or static electricity.
