Resistors are one of the most important electronic components. They are used to control the flow of current in a circuit and are available in various types and sizes. The type of resistor you need will depend on the application for which it is being used.
Fixed Resistors
Fixed resistors are the most common type of resistor used in electronic circuits. Fixed resistors are available in various types, including metal film, and wirewound. Each type of fixed resistor has its advantages and disadvantages.
Metal film resistors are made by depositing a thin film of metal on a ceramic substrate. They are very accurate and have low noise, but they can be damaged by heat. Carbon film resistors are made by depositing a thin film of carbon on a ceramic substrate. They are very rugged and have good tolerance, but they are not as accurate as metal film resistors.
Wirewound resistors are made by winding a wire around a ceramic substrate. They are very rugged and can handle high power, but they can also be very large. Wire Wounds can be either high power and good tolerance, or lower power and high tolerance.
Thin film and thick film resistors are a type of resistor made from a thin film of material. They have several advantages over other types of resistors. Thin film resistors are very accurate and have low noise, making them perfect for use in sensitive electronic circuits. They are also very small and lightweight, making them perfect for portable devices.
The Bottom Line
In conclusion, resistors come in various shapes and sizes, and each has a specific function in a circuit. By understanding the different resistors and their functions, you can select the right resistor for the job and ensure your circuit is working properly.
