Trimmers, Variable Capacitors are electronic components that allow users to adjust the capacitance value within a specified range. Unlike fixed capacitors, these components provide tunability, making them suitable for applications where precise adjustment of capacitance is required, such as in radio frequency (RF) circuits and tuning circuits. The market price of these components vary based on factors like capacitance range, quality, and brand. Typically, prices range from a few cents to a few dollars per unit. Higher precision and larger capacitance ranges may contribute to higher prices. When purchasing Trimmers, Variable Capacitors, focus on ensuring the capacitance range matches your circuit needs, and consider the size and form factor for compatibility with your circuit design.
