Through Hole Resistors are frequently used in electronic circuits for purposes such as signal attenuation, voltage division, and current limiting. The FCR200JR-73-12K is one such resistor, and is designed to provide a great deal of versatility and reliability. It is specified for a wide range of operating temperatures, from -55 to +125 degrees Celsius, and can handle up to one watt of power. This document will discuss the application field and working principle of the FCR200JR-73-12K resistor.

In terms of applications, the FCR200JR-73-12K is most commonly used in DC circuits as a current-limiting resistors or a voltage-divider elements. Its power rating and resistance remain constant over a wide temperature range, making it ideal for circuit protection applications. For example, it can be used to protect input circuits from over-current conditions. This kind of protection can be especially important in industries dealing with automotive electronics and medical electronics. In addition to these applications, the FCR200JR-73-12K can also be used in RF and microwave circuits as an attenuator, an impedance matching device, a termination resistor, and a DC blocking capacitor.

The FCR200JR-73-12K resistor consists of four port contacts arranged in a cruciform pattern. These port contacts come pre-tinned and are soldered onto an FR4 PCB. The port contacts are made from a high-temperature conductive material which can withstand temperatures up to 250 degrees Celsius. Between the port contacts is an internal ceramic core which contains the resistance element. This ceramic core has two layers which are separated by a layer of glass. The internal resistance element is composed of a resistor film encapsulated in ceramic material. This resistor film is composed of a metal alloy or a semiconductor material.

The FCR200JR-73-12K resistor works by converting electrical current into heat. This heat is then dissipated through the contacts and ceramic core. The resistance value is determined by the thickness of the resistor film. The resistance is stable over a wide range of temperature and humidity levels. The resistance value is unaffected by changes in voltage, current, or temperature.

In conclusion, the FCR200JR-73-12K is a through-hole resistor with a wide range of applications and reliable performance. It is specified for temperatures ranging from -55 to +125 degrees Celsius and can handle up to one watt of power. It is commonly used as a current-limiting or voltage-dividing device in DC circuits, as well as an attenuator, an impedance matching device, a termination resistor, and a DC blocking capacitor. The resistor is composed of four port contacts, a ceramic core, and an internal resistor film. The resistance of the resistor is determined by the thickness of the internal resistor film. The FCR200JR-73-12K is a reliable and versatile resistor that is well-suited for a wide range of applications.
