Through Hole Resistors, also known as axial resistors, are two lead components that come in a cylindrical shape, with terminals extending from each end of the body. The 25J39RE series is a type of through-hole resistor designed to meet a variety of design requirements. This article will look into the application fields and working principle of the 25J39RE.

What is the 25J39RE?

The 25J39RE Series is a general-purpose, through-hole based resistor that provides a large range of resistance values in a low-cost package. The 25J39RE offers high power dissipation over an operating temperature range of up to 200˚C, with a wide resistance range of 1 ohm to 10,000Mohm. It also features an extended lead length for tighter board layout, greater flexibility for handling, and less chance of irritating adjacent components.

Application Fields

The 25J39RE is a versatile product that is ideal for use in a variety of conditions and applications. It is commonly used as a potentiometer, rheostat, or variable resistor, in adjustable power supplies, filament dimmers, and other precision electronic circuits requiring these types of components. Additionally, the high power dissipation and extended lead length makes the 25J39RE well-suited for industrial, commercial, and medical equipment, as well as motor drives, test and measurement, and consumer electronics.

Working Principle

The 25J39RE series is a linear resistor. This means that, when the amount of current flowing through the resistor increases, the resistance of the component increases linearly. This is true up to the point when the power of the component is exceeded, which causes the resistor to heat up beyond its thermal rating, resulting in an increase in resistance. Depending on the rated power of the resistor, this increase in resistance will usually result in permanent damage to the component.

The 25J39RE is able to withstand large amounts of current due to its high power dissipation. This is a result of the body material, which is designed to absorb and spread the heat quickly and efficiently. Additionally, each end of the resistor has a hole that allows for easy attachment to circuit boards or other components, providing greater flexibility in the design of the circuit.

Conclusion

The 25J39RE Series is an excellent option for anyone looking for a precise, cost-effective, and high-power through-hole resistor. It is suitable for a wide range of applications, from consumer electronics to industrial equipment, and its features make it well-suited for use in potentially challenging environmental conditions. Additionally, its linear resistance and easy installation make it easy to work with from a design point of view. With its versatile and reliable properties, the 25J39RE is sure to become a staple in many electronic circuits.
