Through Hole Resistors are an essential component in many electrical designs as they allow for greater precision than alternatives such as surface mount resistors. The SQM200JB-0R47 is a type of through hole resistor that is especially suited for many applications due to its high power rating, long life-time, and low ohmic value. In this article, we will explore the application field and working principle of the SQM200JB-0R47 in detail.

The SQM200JB-0R47 is a through hole resistor with a power rating of 200 watts with a max voltage of 200 volts. This power rating makes the SQM200JB-0R47 a great choice for a wide range of applications including industrial, automotive, and communication electronics. Additionally, the SQM200JB-0R47 has a long life time of up to 150,000 hours, making it a reliable choice for many operations.

The SQM200JB-0R47 has a low ohmic value of 0.047ohms making it able to provide precise resistance values. This property makes the SQM200JB-0R47 a good choice for many current-limiting and power control circuits. They are also well suited for high frequency applications as they exhibit good temperature stability over a wide range of conditions.

The working principle of the SQM200JB-0R47 is based on the concept of voltage division. As the voltage through the resistor increases, the ratio of voltage across the resistor to the total voltage increases. Therefore, the voltage across the resistor is inversely proportional to the resistor’s ohmic value. In other words, the higher the ohmic value, the lower the voltage across the resistor will be. This allows the SQM200JB-0R47 to provide precision resistance values.

In addition to voltage division, the SQM200JB-0R47 also experiences self-heating. As the current flowing through the resistor increases, the temperature of the resistor will increase, leading to a decrease in the ohmic value of the resistor. This is due to the effect of thermal electromotive force, which is temperature induced electric field. The self-heating property of the SQM200JB-0R47 allows for precise control over the resistance value, allowing for more precise power regulation.

The SQM200JB-0R47 is a reliable and precise through hole resistor that has many applications. Its precision voltage division and self-heating properties make it suited for many current-limiting and power control circuits. In addition, its long life-time and wide operating temperature range make it a great choice for many industrial and communication electronics applications.
