Through Hole Resistors

WW3JB390R is a type of through hole resistor. It is designed mainly for AC line filter applications, offering low noise, low current consumption, high frequency response, and high stability under conditions of high temperature and vibration. This makes it suitable for a range of industries, including medical, automotive, and military applications.

Working Principle

The WW3JB390R operates on the principle of resistive attenuation. A resistor is a device that changes electrical energy, which is measured in volts, into another energy form, such as heat or mechanical motion, measured in watts. A resistor will reduce the electrical current, resulting in a decrease in the overall voltage. This decrease in voltage is called attenuation, and it is this principle the WW3JB390R uses to achieve its function.

Structure and Components

The WW3JB390R is constructed with a ceramic body, a pair of metal contacts, and an element made of aluminum oxide or nickel-zinc ferrite material. The resistor is built with two parts: a positive plate, which forms the most conductive path from the power source and forms the most resistance, and a negative plate, which forms the least conductive path and is less resistant. This setup creates a unique structure that is highly effective in controlling electrical current.

Other Applications

In addition to its use in AC line filters, the WW3JB390R can also be used for surge protection, high voltage power supplies, and motors. It also has some applications in data communications, telecommunication equipment, and various other electronic devices.

Conclusion

The WW3JB390R is a type of through hole resistor with many applications. It operates on the principle of resistive attenuation, using a ceramic body, metal contacts, and an element made of aluminum oxide or nickel-zinc ferrite material. It is suitable for AC line filters, surge protection, high voltage power supplies, motors, data communications, and telecommunication equipment.
