Furthermore, they can be used for the power supply of low-voltage DC circuits, as well as to limit energy in applications that involve high current such as solar cells and batteries.

Working Principle

WW1FT1R21 resistors consist of a non- conductive substrate made of ceramic and a resistor element rolled into a thin fitting. It also features an adhesive that will help with the proper adhesion of the resistor to a plastic car or dielectric.The resistor element consists of an alloy that is composed out of high-resistance, which helps the resistor control the electric flow. The metal alloy, when brought in contact with an electric current, produces heat. This heat is what the resistor element uses to control the current and the temperature of the resistor. The temperature of the resistor is kept at a constant level using a cooling agent such as air or water.WW1FT1R21 offers a variety of resistors for different applications. They come in various form factors such as miniature, powdered and resistive networks. The resistance can range from 0.1 ohms to 5 Megohms. The operating temperature range is from -55°C to +280°C with a tolerable tolerance ratio of 1%.The most important characteristics of this type of resistor is that it’s accurate, durable and highly resistant, which makes it suitable in any application where the exact value of the resistance is essential.

Conclusion

WW1FT1R21 through hole resistors are an example of the great performance that through hole resistors can provide. They are designed to meet the current and temperature requirements of industrial equipment, telecommunications systems, consumer electronics and automotive applications. Working principles of these resistors are based on the way the resistors element resist electricity flow. Furthermore, WW1FT1R21 resistors offer a variety of resistors for different applications with resistance options that range from 0.1 ohms to 5 Megohms. All of these together explain why they are so commonly used in many commercial equipment such as wireless base stations, digital switching systems, and radio frequency instruments.
