Through Hole Resistors are electrical components that are intended to control the current and voltage in a circuit by providing a fixed resistive value. One such example of this is the CB3JBR240 resistor. This resistor offers an optimized working range and a form factor that is well suited to a variety of applications and industry standards.

Application

The CB3JBR240 is a solution for current or voltage limiting, voltage drop and the stabilization of oscillator and amplifier circuits. It is a through-hole resistor designed for use in industrial, automotive, consumer and telecommunication systems. It is available in a variety of form factors and mounting configurations making it suitable for design in space-constrained applications as well as those requiring greater heat dissipation. The CB3JBR240 is RoHS compliant and is designed to operate in a wide temperature range up to 105°C.

Features

This resistor features a solid metal construction with a removable bottom cover for easy mounting and handling. It offers improved reliability due to its low ESR (equivalent series resistance) and high ripple current rating. Additionally, it features a ruggedized construction for superior long-term performance. The CB3JBR240 has a temperature range of -55°C to +105°C and a thermal time constant of less than 3 seconds.

Working Principle

The working principle of the CB3JBR240 resistor is based on Joule\'s law of heating, which states that the power dissipated by the resistor is equal to the square of the current passing through the resistor multiplied by the resistance value. This law is used to calculate the power dissipation of the resistor and its limits. The resistor works by converting the current to heat, thereby limiting the amount of current that flows through it. This resistor is designed to be connected to a circuit, with the current going in one direction and the voltage going in another direction.

The CB3JBR240 also features an integrated copper plated heat sink to improve dissipation efficiency. The heat sink increases the surface area of the resistor, allowing for a better heat transfer to the ambient air. This contributes to the improved power handling of the resistor and the longer life expectancy.

In conclusion, the CB3JBR240 provides an optimal working range due to its reinforced construction, its wide temperature range, and its low ESR. It is an ideal solution for current or voltage limiting, voltage drop and the stabilization of oscillator and amplifier circuits. This resistor is suitable for use in a variety of industrial, automotive, consumer and telecommunication systems and it is compliant with a range of industry standards.
