Adjustable Power Resistor has widely been used in many fields for its excellent performance and properties. One type of the Adjustable Power Resistor is D75K500, which mainly applies to the space of low heat dissipation and low cost.

D75K500 is composed of a resistor and an adjustable slit, which can change the area of the contact when it is turned, thus it can adjust the resistance. Equipped with a helical spring, the adjustable slit can fasten and maintain the contact.

The working principle of D75K500 can be divided into two main steps. Firstly, the adjustable slit can be easily turned, which exerts pressure against the helical spring. Secondly, as the adjustable slit turns, its lower contact is in contact with the upper contact. During the process, the area of the contact changes and thus we can get an adjustable resistor with a different resistance.

Due to its unique design, features and parameters, D75K500 has been widely used in many fields. It has been installed in many industries, including computer, communication, automotive, aviation and military electronic products. It is also applied in test equipment and medical equipment. With its excellent heat dissipation and high reliability, D75K500 can effectively guarantee the safety of electrical equipment and circuits.

In addition, D75K500’s low cost also makes it popular. It is an ideal choice for low cost applications. It can also replace other resistors, such as wirewound resistors and ceramic resistors in low power applications, thus greatly reducing the cost.

D75K500 adjustable power resistor also has some disadvantages. Its resistance range is narrow and can only be adjusted between 0.1 ohm and 10 ohms. It also has a larger resistance drift when the temperature changes, so it is not suitable for applications that require high stability and precision.Therefore, before choosing this type of resistor, users need to carry out a comprehensive evaluation and decide whether it is suitable for the application.

In conclusion, D75K500 adjustable power resistor is an ideal choice for low power applications with low heat dissipation and low cost requirements.
