Through Hole Resistors are electronic components widely used in electrical circuits and devices. They provide a resistance or isolation between two electrical conductors. One of the most commonly used through hole resistors is the 40J2R2E, which is manufactured by several companies. This resistor has a wide range of applications, from transistor oscillators to high voltage applications.

The 40J2R2E is a through-hole resistor with a tolerance of 5%. It has a maximum power rating of 4 Watts and a maximum voltage rating of 200 Volts. The resistance range is between 2 and 20 Ohms with a 2 Ohm step. It has a Class-O per MIL-R-39017/1-QR/309 specification with mounting spacing on 0.250" centerlines.

The 40J2R2E has a relatively low resistance tolerance, which means that the actual resistance value is approximately 5% higher or less than the nominal resistance value. This variation in the resistance value is due to the material composition of the resistor. In addition, the resistor has a lower power rating than higher rated resistors, making it suitable for lower voltage applications. The 40J2R2E is also characterized by its high reliability and long life.

The 40J2R2E is ideal for applications where the circuit cannot handle higher power nor exceed the maximum voltage rating. An example would be an oscillator circuit where the oscillation level must be kept within a certain range. The resistor\'s high reliability ensures that the oscillator circuit will operate within the specified range for a long time. Other applications of the resistor include motor control, active filters, and signal conditioning.

The 40J2R2E is primarily used in through-hole boards. It can be soldered into the board using traditional soldering methods such as point-to-point soldering or wave soldering. The resistor is also available in through-hole mount designs, which are designed for surface mounting on the board. These designs are available in a wide range of sizes and shapes, depending on the application and size of the resistor.

The working principle of the 40J2R2E is based on Ohm\'s law. According to Ohm\'s law, a current flows through a resistor when a voltage is applied across it. The resistance of the resistor determines the amount of current that can flow through it. The 40J2R2E is designed to dissipate a certain amount of energy, operating within a certain temperature range. When the current that passes through the resistor exceeds the maximum current rating, the resistor will overheat and suffer permanent damage.

The 40J2R2E is an effective and reliable single-turn through-hole resistor. It has a wide range of applications and is suitable for a variety of electronic circuitry. The resistor has a good tolerance level and is available in a variety of form factors. It is an essential component in many electronic projects.
