Through hole resistors are an important and ubiquitous electronic component. The LR2F130K is a selector based resistor, which utilizes a rotating contact to select various resistive values in a single device. It is a three terminal device with a 3/8-inch body diameter that can be installed in standard through hole applications, making it very accessible to design engineers.

The LR2F130K has a wide range of resistance values, varying from 15 ohms to 130 kilo ohms. This makes it ideal for a number of different applications, including both fixed and variable resistance uses. Key features of the LR2F130K include its power handling capabilities, with ratings of up to 5 watts; a very low thermal coefficient, meaning it maintains its resistance even under high temperature variations; and an accuracy of ±5 %, providing dependable performance in all conditions.

The working principle of the LR2F130K is relatively straightforward. As the selector knob is rotated, it turns a cam that engages the resistive element inside the device. When the cam is turned, a graphite material is pressed onto a resistive track that is made of ceramic material. Depending on how far the cam is turned can select different resistance values, up to 130K Ohms.

The range of applications for the LR2F130K is vast. It can be used to control flow of current in electronic circuits, to act as a voltage divider, as part of a voltage regulator, or even as part of a relay circuit. Other potential uses of the LR2F130K include power supplies, audio amplifiers, and RF communication systems.

The LR2F130K is a high performance robust component that is relatively easy to install and use in electronic systems. Its flexibility makes it an ideal choice for a wide variety of applications where accurate and controlled resistive systems are needed.
