Through Hole Resistors

Through hole resistors are an essential component in a great variety of electrical and electronic systems. They are widely used to regulate current or voltage by providing a known resistance at a fixed value. They are commonly seen in power supply circuits, feedback and voltage division networks. Some of the more common uses are for temperature and light sensing, as well as isolation of digital signals.

The FKN300JR-73-0R56 is a through hole resistor manufactured by Laplace and commonly used in automotive, power, aerospace and defense applications. It is composed of a metal core surrounded by cermet material and insulation for easy handling and mounting. The metal core provides the electrical conductivity for the current, and the cermet material provides the necessary electrical resistance. This makes the device ideally suited for high power applications with high current and frequent changes in temperature.

The working principle of the FKN300JR-73-0R56 can be seen in the following equation. When a current travels through the resistor, the electrical power lost is equal to the resistor\'s resistance multiplied by the square of the current:

P = R X I²

This relationship holds even at high current, where the power lost is the highest and at lower current, where the power lost is the least.

In addition, the FKN300JR-73-0R56 has a low thermal coefficient, meaning that the electrical resistance of the device is not greatly affected by changes in temperature. This is an important feature in automotive, power, aerospace, and defense applications, especially in environments where extreme temperature fluctuations may occur.

The FKN300JR-73-0R56 through hole resistor is a rugged and reliable component, ideal for high power circuits. It is composed of a metal core and cermet material for excellent performance and long life. In addition, its low thermal coefficient ensures that the resistance remains unchanged over a wide temperature range. As such, it is the perfect choice for automotive, power, aerospace, or defense applications.
