Fixed Resistors

Fixed resistors are passive electronic components that are used to resist the flow of electric current in a circuit. They have a fixed value of resistance, meaning their resistance cannot be adjusted once they are manufactured. They are commonly used to set the bias of transistors, control the gain of amplifiers, or limit the current flowing through an LED. Fixed resistors come in various sizes, power ratings, and tolerances.

There are two types of fixed resistors: through-hole and surface mount. Through-hole resistors have leads that are inserted into holes on the printed circuit board (PCB), while surface mount resistors have terminals that are soldered directly to the surface of the PCB. Through-hole resistors are larger and easier to work with, but surface mount resistors are smaller and more suitable for miniaturized electronic devices.

Fixed resistors can be made from a variety of materials, including carbon, metal, and wire-wound. Carbon resistors are inexpensive and widely used, but they have a lower tolerance and are more susceptible to noise than other types. Metal film resistors have a higher tolerance and better stability, making them ideal for use in precision circuits. Wire-wound resistors have a higher power rating and are used in high power applications, such as power supplies and amplifiers.
