Chassis Mount Resistors

The WFH160L50RJE is type of chassis mount resistor. It is designed for installation onto a printed circuit board (PCB) or a chassis. These resistors are cylindrical, and usually range from 10 ohms to 5 megaohms in resistance. They usually have a power rating between 1/4 and 1 watt, but higher power models are also available. Most commonly, these resistors are used to combat voltage and current abnormalities, and are used as part of a shunt circuit.

Characteristics

The WFH160L50RJE has a pin diameter of 0.236 inches, and a pin spacing of 0.406 inches. It has a resistance tolerance of +/- 0.5 and a voltage rating of 50 volts. The temperature coefficient is 0.05%/°C and the power rating is 1/4 watt. It is designed to be footprint compatible with the WMF16S50RJE resistor. It is rated for operation up to 85°C, and in humidity up to 95%. The resistor consists of a non-polished carbon film material with a standard axial component package.

Resistor Construction

As a chassis mount resistor, the WFH160L50RJE is composed of a number of components with different functions. It has a metal-oxide film element (MOF) which connects two terminals, as well as a resistor element which is used to vary the resistance between the terminals. This element is typically formed into a metal film resistor, which is encased in an insulating epoxy coating. The insulating epoxy coating also serves to protect the resistor element from foreign objects. Additionally, the resistor element is connected to the metal-oxide film element via a leaded adhesive. This allows for a secure connection between the two parts and prevents any electrical shorts.

Application field and Working Principle

The WFH160L50RJE chassis mount resistor is commonly used for voltage and current regulation applications. It is most commonly used in shunt circuits, where it is used to balance the voltage and/or current across the circuit. In a shunt circuit, the resistor is placed in parallel with the main circuit and its resistance is adjusted to either increase or decrease the current or voltage. This can be done by either shortening or lengthening its leads, which affects the resistance value of the resistor.

The WFH160L50RJE can also be used to decrease the voltage of a circuit, which is done by placing the resistor in series with the circuit. In this application, the resistance of the resistor is chosen so that the circuit\'s voltage is reduced to the desired amount. This can be done to protect circuit components from damage, or to simply reduce the overall power consumption of the circuit.

The WFH160L50RJE can also be used for measuring current and/or voltage. As the resistor is placed in series with a circuit, the current or voltage can be measured across the resistor. By measuring the voltage drop across the resistor, the current or voltage can be determined. This can be used to measure the load on a circuit, as well as to measure the other electrical parameters of the circuit.
