Through Hole Resistors

Through hole resistors are one of the most common electric components available and have a wide range of uses. They are two-terminal resistors that can be used to limit the current flowing through a circuit, as well as providing noise suppression or temperature compensation. They are available in various package sizes and with multiple resistance values.

The 40J120E is a through hole resistor designed to be mounted through a PCB board. It has a maximum power rating of 2 watts and an operating temperature range from -25℃ up to +85℃. In terms of maximum temperature this puts it on the high end of the range. This makes it ideal for applications that require higher levels of heat or long periods of operation.

Applications of 40J120E

The 40J120E is most commonly used in DC/DC applications, where the load is connected directly to the mains. Examples of this include consumer electronics and domestic appliances. It can also be used in higher power applications, such as motor control or power management. The higher power rating and temperature range also make it suitable for industrial applications.

The 40J120E is also commonly used in AC applications, such as lighting circuits or motor control. It is able to handle high levels of current in these applications, helping to protect the circuit from damage. It can also be used to provide noise suppression in audio systems. This helps to provide a more stable output.

Working Principle of 40J120E

The working principle of the 40J120E is simple but effective. It works by creating a resistor between the two terminals. This resistor provides a resistance in the circuit, thus limiting the flow of current. The value of the resistor can be changed by adjusting the resistance element inside the resistor, which means it can be adjusted to suit different applications.

The resistor also provides noise suppression in an AC system. This helps to reduce the high-frequency noise and hum that can be generated from certain appliances. The resistor also works as a temperature compensator, helping to ensure a stable output in environments with varying temperature conditions.

Conclusion

The 40J120E is a through hole resistor which is designed for use in AC and DC applications. It has a maximum power rating of 2 watts and an operating temperature range from -25℃ to 85℃. It is most commonly used in consumer electronics and domestic appliances, as well as providing noise suppression and temperature compensation in audio systems. The principle of operation is to provide a resistor between the two terminals, which helps to limit the current flow and provide stability even in extreme temperature conditions.
