45F7R5

Through Hole Resistors come in many shapes and sizes and can be used for a variety of applications. One such type is the 45F7R5, which is uniquely suited for use in medium to high power circuits and can handle a wide range of voltages. It is a 4-terminal device that provides stable resistance values across the full range of operating temperatures. The 45F7R5 is an ideal choice for applications such as power supplies, Audio/Video equipment, Instrumentation, and Telecommunications.

The 45F7R5 is a metal-oxide-film resistor, which utilizes a unique composite dielectric material that gives it superior performance characteristics. The resistor contains two metal plates - a substrate and top-layer material, and a conducting layer between them. The conductivity of the resistor is determined by the composition of the top-layer material. The metal film is then heated in a vacuum, causing it to expand and fill-in the grooves and irregularities that were formed during the application of the metal. This process gives the resistor its unique resistance value and its ability to handle higher currents and voltages.

The 45F7R5’s application range is quite wide and can cover a voltage range of up to 140 volts. It has a power rating of up to 7.5 watts, so it is suitable for use in medium to high power circuits. The low temperature coefficient makes it ideal for applications where temperature stability is important. Its temperature range is -55°C to +105°C, with an isolation resistance of up to 1000 mega-ohms. This makes it suitable for use in higher temperature applications, such as high temperature test equipment, audio amplifiers, and industrial process control.

The 45F7R5’s operating principle is simple. A voltage is applied across its two terminals, causing a current to flow. This current is proportional to the applied voltage, as well as the resistance of the resistor. As the temperature of the 45F7R5 increases, the amount of current that can flow through it also increases, as the resistance of the resistor decreases. This leads to a higher dissipated power, as the amount of energy being transferred grows. Conversely, as the temperature decreases, the resistance of the resistor increases, leading to a decrease in the dissipated power.

The 45F7R5 is a relatively easy device to use, as its operating principle is simple and straight-forward. Its four terminals make it easy to install in a circuit. It can be used as an ideal resistor in most medium to high-power circuits, and its temperature stability makes it suitable for high temperature applications. The 45F7R5 is an excellent choice for applications such as power supplies, audio/video equipment, instrumentation, and telecommunications.
