Trimmers, Variable CapacitorsTrimmers, also known as variable capacitors, are a type of electronic component that is used to adjust the capacitance of a circuit. These capacitors are commonly used in applications where a variable capacitance is needed, such as in tuning circuits or impedance matching circuits. Trimmers are typically small, adjustable capacitors that can be easily adjusted using a screwdriver or other tool. They are often used in conjunction with other electronic components, such as inductors or resistors, to provide a tunable circuit that can be adjusted to meet the specific needs of a system or application.
