20JR50E

Through Hole Resistors are commonly used in various electrical applications. The use of these devices is primarily for controlling or limiting current flow in a circuit. They are popularly used as current-limiting resistors, voltage-related resistors, or simply as resistors that ensure the correct operation of other components. A common example is the 20JR50E Through Hole Resistor which is widely used in many industrial and consumer applications.

Overview of 20JR50E

The 20JR50E Through Hole Resistor is an energy-efficient, thermally protected resistor with a maximum power rating of 50 watts. It is designed for applications within up to 65 °C environment and is primarily used in circuits that require alternating voltage. The 20JR50E resistor has an initial tolerance of ±5% and nominal resistance value of 20 ohms. It is a thermally protected type that provides enhanced stability and reliability in performance. The device is designed to detect and regulate excessive temperature levels by limiting current flow from the device.

Applications of 20JR50E

The 20JR50E Through Hole Resistor is primarily used in industrial and consumer applications such as air conditioning, power tools, motors, lighting, refrigeration, and home appliances. It is also widely used in electrical circuits such as LED lighting control, motor speed control, and voltage regulator circuits for power systems. In addition, it is commonly used in audio systems for load matching, amplifier protection, and current limiting.

Working Principle of 20JR50E

As previously mentioned, the 20JR50E Through Hole Resistor is an energy-efficient, thermally protected device. As current passes through the resistor, the resistor’s body temperature increases due to Joule heating. When the maximum allowable temperature is exceeded, the resistor’s safety epoxy melts and causes the circuit to open, thus limiting the current flow from the device. In addition, the 20JR50E resistor has a temperature-sensitive resistor embedded in its body. When the temperature increases, the resistor’s resistance also increases, thus forcing current to bypass the resistor and preventing any further damage caused by excessive temperature levels.

Conclusion

The 20JR50E Through Hole Resistor is a popular device used in many industrial and consumer applications. It is designed with an integrated thermal protection system to prevent any damage due to excessive current flow. In addition, the device is energy-efficient and has an initial tolerance of ±5%, making it an ideal choice for current-limited applications and LED lighting control systems.
