OK8225E-R52

Through Hole Resistors

A through hole resistor is a kind of electrical component that provides resistance in an electric circuit. It is one of the most common, and most basic, components used in electronic products. It is typically a circular wire loop made of a metal strip, or a cylindrical metal core, and is soldered into place at both ends onto a circuit board. The resistance of the component can be adjusted by changing the size of the wire loop, and by changing the material used for the metal strips.

The OK8225E-R52 is an example of a through hole resistor. Manufactured by OK Electronics, the OK8225E-R52 is a throughhole, double-sided SMT resistor, and is designed for surface mount application in high temperature environments. It has numerous features which make it ideal for applications requiring high-temperature operation with high resistance values and low-loss characteristics.

In terms of its application fields, the OK8225E-R52 is most commonly used in automotive, power, and lighting applications. It is often used as part of a voltage-dropping pair, where two resistors are used to regulate the power output of a system. In automotive systems, it is often used to control the fuel injection system, while in lighting systems, it is used to control the amount of current flowing to the light sources. In power applications, it can be used to protect sensitive circuits from overloads.

As for the working principle, the OK8225E-R52 is a kind of "fixed resistance" resistor. This means that the resistance of the component remains constant throughout its lifetime, and is not affected by temperature or other external factors. The component is made up of a metal strip or cylinder, which can be either insulated or uninsulated, depending on the application. The resistance is determined by the size of the metal strip/cylinder, and the type of material used. Since the resistivity and material used remain constant, the only factor that can change the resistance is the size.

In conclusion, the OK8225E-R52 is a through hole resistor designed for use in high temperature environments, and is often used in applications where high resistance values and low-loss characteristics are required. It is a fixed-resistance type resistor, meaning the resistance is determined by the size of the metal strip/cylinder, and the material used. Through hole resistors are integral components of many electronic products, and the OK8225E-R52 is a reliable and cost-effective option for industrial and commercial applications.
