Through Hole Resistors are among the most popular, commonly used, and dependable types of resistors available in the market. The 45FR40E Through Hole Resistor is a precision resistor designed for a variety of applications, including high-speed switching, pulse shaping, and filter design. It has a very low resistance tolerance of ±0.1% and temperature coefficient of ±25ppm/°C, making it suitable for highly accurate, reliable, and stable performance in electronic designs.

The 45FR40E Through Hole Resistor is available in a wide range of standard and custom footprints, allowing it to fit into tight spaces and making it suitable for use in space-constrained applications. It can also be used for both top-side and bottom-side wiring. The resistor is constructed from a thin-film material which uses a combination of resistive and dielectric layers to ensure high precision and low temperature coefficient. It also features a wide range of operating temperatures, from a minimum of -55°C to a maximum of +150°C.

In terms of application field, the 45FR40E Through Hole Resistor is commonly used as reference resistors for ADC and DAC. Its excellent temperature coefficient and low resistance tolerance make it ideal for these applications where high accuracy and stability of the output is required. It is also commonly used as a voltage divider in power circuits where it can provide precise output voltage ration. Additionally, the 45FR40E Through Hole Resistor is often used as a signal amplifier, as the resistor\'s low temperature coefficient and low resistance tolerance ensure consistent and accurate performance over a wide temperature range.

The 45FR40E Through Hole Resistor features a unique construction that utilizes a metallic foil material for the resistive and dielectric layers. The foil material itself is very thin and is embedded into a slightly thicker plastic body. The plastic body increases the life expectancy of the resistor as well as provides better protection from environmental conditions. This foil metal construction also serves to reduce the temperature coefficient of the resistor, enabling it to operate over a wider temperature range than other resistors in its class.

As for the working principle of the 45FR40E Through Hole Resistor, it follows the standard ohmic law. In this law, the voltage across the resistor is inversely proportional to the current running through it. This means that if the voltage across the resistor is increased, the current running through it will decrease, and vice versa. The resistor will also change its resistance as the temperature changes, but due to the low temperature coefficient design of the 45FR40E Through Hole Resistor, the change is minimal.

In conclusion, the 45FR40E Through Hole Resistor is a precision resistor designed for a variety of applications, including high-speed switching, pulse shaping, and filter design. With its wide range of standard and custom footprints, its low resistance tolerance of ±0.1%, and its low temperature coefficient of ±25ppm/°C, the 45FR40E is perfect for designing high accuracy, reliable, and stable electronic designs. Additionally, its foil metal construction helps to reduce the temperature coefficient of the resistor, enabling it to operate over a wider temperature range than other resistors in its class.
