Through Hole Resistors are ubiquitous components for most electrical and electronic systems. The PWR221T-30-33R0J specifically is a through-hole resistor that belongs to an organization\'s metal-oxide-film resistor portfolio. These resistors are characterized by their ≤ 0.05% tolerance, over-temperature protection feature, and long-term stability. The main application field of the PWR221T-30-33R0J through-hole resistor lies in precision control systems, such as those used in machine tools, solar inverters, and medical equipment. However, this resistor has found application in many other fields, such as consumer, automotive, industrial, and communications systems.

Working Principle

The PWR221T-30-33R0J uses a metal-oxide-film resistor element to attain its resistance. The resistance value is achieved by varying the thickness of the protective coating, which is usually composed of tin-oxide and cermet materials. By adjusting the thickness of this protective coating, the resistivity of the component can be regulated within a specified range. The resulting resistors have good temperature stability, low noise, and good electrical performance.

The key feature of the PWR221T-30-33R0J is its temperature-compensated design. The protrusions on the resistor body help to keep the resistance constant over a wide range of temperatures. The aluminum-alloy housing ensures maximum dissipation of heat, allowing for enhanced thermal performance. There is also an in-line resistor that is used to reduce the temperature coefficient of the power resistor. This feature ensures that the resistor is able to work in high-temperature environments without risking thermal failure.

The PWR221T-30-33R0J also features a high-resistance tolerance. This is attained by using a precise resistive element that is enclosed in a protective coating. This coating ensures that the resistor is able to maintain its resistance value despite temperature fluctuations. The resistance tolerance is improved due to the precise construction of the resistor element, resulting in extremely accurate readings.

The resistor also has a wide-range of thermal protection. This feature provides the resistor with the highest level of protection against thermal failure. The over-temperature protection feature prevents the resistor from failing due to high temperatures, making it ideal for many applications where high temperature performance is required. This prevents the resistor from being damaged due to excessive heat, providing reliable operation in extreme temperature environments.

The PWR221T-30-33R0J is also known for its long-term stability. This is due to the use of a special Kapton-film construction, which enables the resistor to remain stable for a longer duration of time. The Kapton-film construction also reduces drift, ensuring that the desired resistance value is maintained over long periods of time. This ensures that the PWR221T-30-33R0J is able to offer precise readings over long periods of time, making it the perfect choice for applications where long-term stability is a must.

The PWR221T-30-33R0J through-hole resistor is a versatile component that finds application in several fields. Its features such as excellent temperature compensation, over-temperature protection feature, and high-resistance tolerance make it an ideal choice for precision control systems, consumer, automotive, industrial, and communications systems. Its Kapton-film construction enables the resistor to remain stable for long periods of time, enabling reliable performance in extreme temperature environments. The PWR221T-30-33R0J is an ideal choice for a wide variety of applications.
