Application Field

UAL50-12RF8 are ideal for power supplies applications as they have high power rating, wide resistance range, and good linearity. This type of chassis mount resistor can be used to regulate current and voltage, providing stable load conditions for electrical and electronic components. UAL50-12RF8 can also be used in instrumentation, as they have good temperature coefficient, wide temperature range, and high stability. This makes them ideal for precision measurements and measuring devices. In addition, UAL50-12RF8 can be used in power amplifiers for limiting the peak power that the device can output. This helps to protect the circuit from being damaged by excessive current.

Working Principle

UAL50-12RF8 is a wirewound device, which means it is made of a wire that is wrapped around a core. The resistance of the wire is determined by various factors such as the wire diameter, the core material, and the number of wraps. The core material used for UAL50-12RF8 is usually ceramic, which helps to reduce the temperature coefficient of the device. The resistance of the device can be adjusted by changing the number of wraps around the core. The resistance can also be changed by altering the core material, though this requires more specialized expertise.

The current flowing through UAL50-12RF8 is proportional to the applied voltage, giving rise to a linear resistance feedback. This means that UAL50-12RF8 can be used to regulate current and voltage levels, helping to maintain stable load conditions. Additionally, since the wirewound device is enclosed in a metal housing, it provides reliable protection against vibrations and other environmental factors.

Conclusion

UAL50-12RF8 is a type of chassis-mounted resistor that can be used for a variety of applications. It has a high power rating, good temperature coefficient, wide resistance range, good linearity, and high stability which make it suitable for use in power supplies, instrumentation, and power amplifiers. Additionally, its working principle involves the use of a wirewound device enclosed in a metal housing, which provides reliable protection against environmental factors.
