Through Hole Resistors

Through-hole resistors of many varieties are available today, many of which are designed specifically for industrial, military, and aerospace applications. One example is the CMF55273R00FHEB, a low-cost, high-precision, through-hole resistor that is designed for use in precision analog and digital circuits. This resistor is ideal for use in precision amplifiers, analog-to-digital converters, transimpedance amplifiers, precision voltage references, and instrumentation circuits.

The CMF55273R00FHEB features three component areas: the body, the guard, and the internal resistor element. The body is made of gold-plated copper alloy and is several millimeters in diameter. The guard is made of polyimide and provides shielding from external sources of noise. The internal resistor element is made of a highly alloyed, lead-and-tin-free, high-tolerance resistor element.

This resistor is designed to operate in the range of 0.5 volts to 25 volts and offers very low values of resistance. Its resistance tolerance is exceptionally low at ±0.2%, which allows for extremely precise design accuracy and stable operation. Also, its low temperature drift of just 6 ppm/°C ensures reliable, repeatable performance over wide temperature ranges.

The CMF55273R00FHEB resistor offers excellent electrical characteristics due to its high-precision resistor element and tight tolerance packaging. It also offers excellent stability under varying conditions thanks to its low thermal drift rating. For engineers who require a reliable, high-precision resistor for critical applications, the CMF55273R00FHEB will provide a cost-effective, highly reliable solution.

The working principle of this through hole resistor is based on the electrical phenomenon of resistance. The resistor is composed of an electrical conductor with a metallic coating, which constricts the flow of electric current through the material. The amount of current that can pass through the material is directly proportional to the amount of resistance presented by the material. In other words, the resistance of the material determines how much current will pass through it.

The resistance value of a resistor is determined by its length, cross-sectional area, and the material it is made of. The resistance of a through hole resistor is determined by the length of the conductor, its diameter, and the type of metal used. The longer the metal wire, the higher the resistance will be. Additionally, thicker metal wires will also have higher resistance values than thinner wires.
