Through Hole Resistors
A 33J30RE application field includes the traditional linearity and precision resistor. Designed for demanding applications requiring resistance from 2W to 10W. A 33J30RE resistor is a cost-effective solution to general industrial, commercial, aerospace, and military applications. Its powder epoxy construction provides superior heat and humidity resistance and superior mechanical strength. The 33J30RE also offers excellent high-temperature performance for use in a wide range of environmental conditions.
Working Principle
The electrical resistance of a resistor is a measure of the ability of the resistor to convert electric current to heat. When a current passes through a resistor, the electric energy of the current is converted to heat, which is dissipated in the form of heat radiation. The amount of current is determined by the voltage across the resistor, the resistance of the resistor and the total gain of the device. As the voltage and resistance increase, the current decreases and the power of the device increases.
All resistors contain a basic element that produces an electric field when a voltage is applied across it. This electric field affects the motion of electrons passing through the resistor, producing a heating effect. This heating effect is proportional to the power of the resistor.
The body of the resistor must also be able to dissipate the heat produced by the resistor. The body of the resistor is usually made of a material that can disperse the heat quickly and evenly, such as a ceramic body. The resistance of the resistor depends on its resistance elements, temperature, and the amount of current passing through it. As the temperature increases, the resistance also increases. As the current increases, the resistance decreases.
The construction of the 33J30RE resistor consist of the usual combination of a metal or ceramic body, internal resistance elements, and a terminations. The internal resistance elements could take the form of power dissolution film, carbon composition, or a wirewound design. The body of the device is commonly constructed from a metal powder epoxy or ceramic material. The termination could be a lug type, PC mount, or SMD top termination.
The 33J30RE resistor provides a cost effective and reliable solution with superior longevity, making it ideally suited for harsh or challenging industrial and automotive applications. The resistance range of the resistor provides better accuracy and less drifting over long cycles preventing any drift issues associated with analog designs. This resistor is also extremely low profile, making it easily mountable in tight areas and easily incorporated into existing systems.
