Through hole resistors, also known as axial lead resistors, are an integrated electronic component. They are typically constructed using a carbon film around an insulating ceramic core, encased in a tubular package with two axially-positioned leads extending from the ceramic core. Comparing to the surface-mount resistors, through-hole resistors are larger in size and easy to hand solder onto circuit boards. The advantages of the through-hole resistors are the ability to handle power on a large scale, and their wide range of resistance. B8J20KE resistors are a type of through-hole resistor.

The B8J20KE is an axial resistor composed of a carbon-film resistor element and epoxy resin coating. This type of resistor has numerous applications, most notably in the telecommunications, consumer electronics, automotive, energy, and commercial sectors. In particular, the B8J20KE excels in areas which require maximum power output and heat dissipation capabilities. Its epoxy-resin coating adds protection and ensures durability of the resistor.

The core feature of the B8J20KE is its power rating. This type of resistor has an exceptionally high power rating of 20 Watts; thereby allowing larger currents to be applied without the risk of the resistor overheating. This power rating is greater than most through-hole resistors and provides excellent performance in demanding applications. Furthermore, the B8J20KE has a rated resistance of 0.25Ω and a tolerance of 5%, along with alternate resistance tolerance options ranging from 2% to 20%. Additionally, it has a maximum working voltage of 1000V which makes it suitable for use in high voltage applications.

The working principle of the axial lead resistor is simple; it works by controlling the flow of electric current by limiting the voltage and current levels within an electrical circuit. This process is achieved by introducing a set resistance value. Thus, when a current is applied, some of the energy is lost as heat in the resistor, and the remaining energy is dissipated as voltage drops along the length of the resistor. By regulating voltage and current levels, the B8J20KE can be used to create limiters, protectors, and other switches that allow or deny circuits passage of the current.

In conclusion, the B8J20KE resistors represent a great choice for high voltage projects requiring a reliable and safe resistor that can endure a heavy load. The fact that it can be easily and quickly soldered to any circuit board makes it a desirable component in the telecommunications, consumer electronics, automotive, energy, and commercial sectors. Its features also include excellent power and working voltage ratings, a resistance range of 0.25 ohms, and a variety of tolerance options. Additionally, its thermal and electrical properties, durability, and affordability make the B8J20KE a great choice for any application.
