Resistors
This category comprises a range of products that consist of fixed-value resistors and associated mounting accessories. Fixed-value resistors possess a predetermined resistance value that cannot be adjusted, and are used in electronic circuits to control the flow of electric current and provide precise levels of resistance. To simplify the selection process for engineers and designers, fixed-value resistors are organized based on their physical form factor or the method by which they are connected within an end application. Common classifications include through-hole resistors, surface-mount resistors, and resistor arrays. Through-hole resistors typically feature cylindrical or rectangular shapes with leads that are inserted into holes on a circuit board. They are then soldered in place to establish electrical connections. Surface-mount resistors, in contrast, are much smaller in size and are directly mounted onto the surface of a printed circuit board (PCB) without the use of leads. Resistor arrays integrate multiple fixed-value resistors into a single package, saving space and simplifying the assembly process. These can contain resistors with identical or different resistance values. Adjustable or variable-value resistors, such as potentiometers or rheostats, are classified separately from fixed-value resistors. These components provide the ability to vary resistance levels within a specific range and are useful in applications that require variable resistance. In summary, this category includes fixed-value resistors and their corresponding mounting accessories, organized based on their physical form factor or connection method within a circuit. Adjustable resistors, like potentiometers or rheostats, are categorized separately due to their ability to provide variable resistance levels.
