Chassis Mount Resistors are essential components in electronic devices today. They are used to regulate the amount of current passing through a circuit and to act as a safety device against unforeseen power surges and other external electrical shocks. The CJT200390RJJ is one of the most popular varieties of Chassis Mount Resistors due to its reliable performance and rugged durability.

Application Field and Working Principle:

The CJT200390RJJ is an ideal choice for a variety of applications such as industrial, automotive, and consumer electronics. It is designed to provide reliable electrical insulation and prevent short circuits. Its wide temperature range and 100mΩ resistance also make it an ideal choice for a wide range of voltage or current dependent applications. The CJT200390RJJ is a type of non-inductive metal film resistor which is composed of a highly heat-tolerant and rugged body. The resistor is mounted to a chassis using three screws which ensures a secure mount and secure protection against oxidation. The metal film also provides additional protection against UV radiation.

The CJT200390RJJ has a maximum power dissipation of 5 watts and is rated for operation in temperatures between -55°C and +125°C. In order to ensure reliable performance, the resistor must kept in-circuit for over 8 hours before operation, but should not be exposed to extreme temperatures during this period. Furthermore, the CJT200390RJJ should not be operated in an environment that is excessively humid or dusty.

In terms of its working principle, the CJT200390RJJ utilizes the principle of Ohm\'s law to constrain the current passing through the circuit. By regulating the amount of current passing through a circuit, the CJT200390RJJ can regulate the amount of voltage present in the circuit. Resistance is measured using the units of Ohms. By increasing or decreasing the amount of resistance in a circuit (by changing the size of the resistor), the amount of current that can pass through the circuit can be adjusted accordingly. This is how the CJT200390RJJ operating principle works.

In conclusion, the CJT200390RJJ is one of the most widely used Chassis Mount Resistors, providing reliable performance and protection against unforeseen power surges and other external shocks. It is designed to be used in a variety of applications such as industrial, automotive, and consumer electronics. The CJT200390RJ’s working principle utilizes the concept of Ohm’s law in order to regulate the amount of current passing through a circuit. By adjusting the amount of resistance in the circuit, the amount of voltage present in the circuit can be regulated in a safe and effective manner.
