Through hole resistors are passive two-terminal components that resist current flow. 25J800 is a type of through hole resistors which has wide application field and work principles.

Introduction

25J800 is a through hole resistor used to maintain, limit or change of the flow of electric current in the circuit. It helps to derive various output levels from the energy supply systems. 25J800 resistors are three-digit resistors with resistance value between 500 and 999 ohms. 25J800 resistors usually contain short length (approximately 25mm) of cylindrical bar. It is composed of two metallic terminals, which are connected together at one end with a non-conductive material. In 25J800 type the length of the lead is shortened to about 25 mm.

Application Field

25J800 through hole resistors have the maximum rated power of about 2.5 watts. They are mostly used in modern high voltage applications and have found the usage in industrial applications such as in control panels, automotive systems, medical implants, engineering systems and military devices. This type of resistor can also be employed in voltage regulation circuit in order to reduce the voltage levels. As per their applicability in various situations, 25J800 resistors are referred to as high-end resistors.

Working Principle

25J800 resistors work in a very simple way. In most applications, the resistors perform what is known as Ohm’s law. The resistors have an adjustable resistance value which is related to the length of the bar. They basically work by creating a resistive path to the flow of current. This resistance is created by the interaction of the metallic components. Thus, when the current passes through the resistor, it experiences a drop in the voltage level.

25J800 resistors can also exhibit negative temperature coefficient, which means that the resistance of the resistor will decrease when the temperature increases. This is because the temperature increase causes an increase in the mobility of the electrons and thus, reduces the resistance of the resistor.

Conclusion

25J800 is a type of through hole resistor has wide application fields and working principle. They can be used in various applications in control panels, automotive systems, medical implants, engineering systems and military devices. The resistors have an adjustable resistance value which is related to the length of the bar and they work by creating a resistive path that directly affects the flow of current. These resistors also exhibit negative temperature coefficient, which means that the resistance of the resistor will decrease when the temperature increases.
