Through hole resistors have been around for centuries, and they have evolved along with advances in electronic components. One type of through hole resistor that has been widely adopted is the PWR220T-20-2000F. It is a surface mount resistor that provides excellent stability, long-term reliability and moderately high failure rates.

The PWR220T-20-2000F is a through-hole resistor with a resistance range of 2.2kΩ to 20e3Ω. It is made using a thick-film technology that enables high power handling capacity while having excellent temperature stability and long-term reliability. The PWR220T-20-2000F is a popular choice for high power, industrial, automotive and military applications that require a high degree of accuracy and stability.

In terms of application field, the PWR220T-20-2000F is being used in a wide range of applications, from consumer electronics to military applications. It is often used in high power analog circuits where low power surge is necessary, such as motor controllers and power supplies. It is also used in temperature-controlled switching circuits, high stability AC/DC regulators, and high-density DC/DC converters. In terms of reliability, the resistor is rated to operate at temperatures from -55°C to +125°C and has an ESD rating of 8kV.

The PWR220T-20-2000F is a through-hole resistor that utilizes bulk metal construction. This type of construction offers superior performance and reliability compared to traditional film technology. It is well suited to resistive elements with high power or high frequency characteristics, as it will provide excellent stability over extended periods of time. The bulk metal construction also provides maximum thermal conductivity, which helps extend its operational life.

In terms of working principle, the PWR220T-20-2000F utilises a resistive film that is deposited onto a substrate. The resistive film is a composite made from a mixture of conducting and insulating materials, and it can be easily tuned to a specific value of resistance. This resistive film is then connected to a pair of metal contacts (which form the leads of the resistor) and a substrate material. The leads and the substrate are then coated with insulating material, to prevent contact with other components and prevent leakage. The resistance of the resistor is adjustable by increasing or decreasing the amount of resistive film on the substrate.

The PWR220T-20-2000F is a great choice for a wide range of applications due to its high power handling capacity, excellent temperature stability and long-term reliability. Its construction and working principle also allow it to offer superior performance compared to traditional film technology, making it a great choice for high power analog circuits and high-density DC/DC converters.
