Chassis mount resistors are a type of fixed resistors. The F55J4R0E is one such chassis mount resistor. Its primary components are a wire-wound resistor element and a ceramic, porcelain, or plastic enclosing housing. The resistor displays a greater physical size than its newer counterparts with its 95mm long body. The resistor can be connected to a device by screwing it into the side or by soldering into a printed circuit board.

Coupled with its vast size, the F55J4R0E is capable of boasting significant power capabilities. It is constructedfrom two nickel-chrome alloy wires that are wound around ceramic cores. This combination allows for it to safely handle peak pulse surge wattages of up to 200W and 150W continuous. Additionally, its thermal cycle (derating) characteristics allow for use in more demanding temperature ranges such as those found in industrial applications.

The manufacturer highly advises that the resistor should only be used for its specified power ratings. This is highly beneficial as the F55J4R0E is made with robust components which ensures that its performance does not deteriorate with time. However, over powering the resistor can cause damage to its internal components and can lead to temperature increases that exceed the expected thermal cycle.

The F55J4R0E can be used in many applications due to its size and power capabilities. It is commonly found in industrial and automotive settings as well as many electrical devices. Its use in automotive settings is mainly found in fan speed control systems and energy conversion systems which require large power dissipation. In industrial settings, it is mainly used as an input resistor and for power conversion and other power type applications.

The working principle of the F55J4R0E is simple. It is designed to resist the flow of electric current and reduce voltage levels. The resistor transforms electrical energy into thermal energy by allowing the current to pass through its two conductive wires, thus creating a resistance. This resistance limits the flow of current and, as a result, decreases total power output. This is beneficial for current-limiting applications by ensuring that the electrical components of a system are only powered up to a certain level.

In conclusion, the F55J4R0E chassis mount resistor is a robust resistor designed to resist high power levels. Its power capabilities and temperature range make it suitable for many different applications. The resistor’s working principle is simple - it reduces current levels by creating a resistance and transforming electrical energy into thermal energy.
