Through Hole Resistors, also known as Through-Hole Technology (THT) or Axial Resistors, are common resistor types that can be found in various electronic systems. The FCR3WSJT-73-1K type is a high power wire wound resistor designed with a ceramic body and metal end plates. The device can handle up to 15A of continuous current in a wide temperature range of -55°C to +200°C. It is used primarily in industrial applications that require high power combined with a good tolerance and stability.

The working principle of Through Hole Resistors is quite simple. A coil of resistive wire is wound around a ceramic or metal core and two metal end plates. The resistance of the resistor is determined by the length and the diameter of the wire, as well as the type of material used. There are also trimming resistors that have adjustable contact points which can be used to create a desired resistance value. The desired resistance value is determined by the contact point’s distance from each other.

The FCR3WSJT-73-1K Through Hole Resistor is particularly suited for higher power applications due to its high power rating and wide temperature range. It offers excellent stability and tolerance when compared to other resistor technologies such as surface mount resistors. The device can be easily used in circuits for DC and AC applications. It is also commonly used in power supplies, motor drives, induction heating systems, and various other industrial applications.

The FCR3WSJT-73-1K Through Hole Resistor is a fairly simple device in terms of its design and construction. The main components of the device are the endplates, core, and conductive wire. The endplates are made of metal and come in various shapes and sizes depending on the model. The core is usually made of a ceramic material which provides the necessary temperature insulation and mechanical protection for the conductive wire.

The conductive wire is composed of either copper or nickel based alloy which has a specific resistance value. The number of turns or layers determines the total resistance of the device. The endplates are insulated from the core and conductive wire, so that the entire assembly is electrically isolated. Once all the components have been assembled, the device is ready to be mounted in a circuit board or system.

Despite being a relatively simple device, the FCR3WSJT-73-1K Through Hole Resistor provides a reliable and cost-effective solution for many high power applications. The device’s wide temperature range of -55°C to +200°C makes it suitable for even the toughest of environments. Its excellent stability and tolerance makes it ideal for precise and reliable control of current, voltage, and temperature.
