Through Hole Resistors

A through-hole resistor is an electronic component consisting of a circular metal disk or rectangular metal bar that is designed to protect the electrical circuit it is part of from too much current or dissipate a known amount of unwanted heat. It is one of the most common components found in electronic equipment.

25J2R2E application field and working principle

The 25J2R2E through-hole resistor is specifically designed for applications that require a high power rating, such as large-scale commercial and industrial applications. This type of resistor works by dissipating electrical energy into heat, allowing the circuit to remain stable and preventing the risk of damage or overloading.The 25J2R2E resistor offers a high power handling capability with a resistance range spanning from 0.005 Ω to 1M Ω. This type of through-hole resistor is capable of dissipating up to 5 Watts of power. It is also available in a wide variety of wattage ranges, including 1/8, 1/4, 1/2, 1, and 2 watts.The 25J2R2E resistor is typically constructed using a ceramic enclosure, with copper terminals which are soldered to the PCB. The ceramic enclosure helps to keep the internal parts of the resistor free from dust and debris which can lead to corrosion.The internal structure of the 25J2R2E is composed of a series of layers which are composed of different materials. At the core of the resistor is a strip of golden wire which is layered with several other layers of metal within the ceramic enclosure. This creates a barrier between the golden wire and the external environment, protecting the resistor from environmental changes.The 25J2R2E resistor also offers several safety features such as voltage and current protection. This helps to protect the circuit from any damage caused by sudden voltage or current spikes. In addition, the resistor also provides protection against overtemperature, ensuring the resistor does not exceed safe operating temperatures.Overall, the 25J2R2E through-hole resistor is an ideal component for applications which require high power and need to be protected against current or voltage fluctuations. Thanks to its robust structure and safety features, it is one of the most reliable and long-lasting through-hole resistors available on the market.
