Definition

Noun: A trimming capacitor is a type of capacitor whose capacitance can be adjusted. It is used to make small, precise corrections or fine-tuning adjustments in an electronic circuit.

Usage

This component is specifically used in electronic circuits where precise calibration is necessary. It allows engineers and technicians to adjust the circuit's performance to an exact specification after the main components are installed.

Examples

• The oscillator frequency was slightly off, so the technician adjusted the trimming capacitor.
• For precise tuning in this radio receiver, you will need to use a trimming capacitor.
• The circuit board includes a trimming capacitor to allow for calibration during the final assembly stage.

Advanced Usage

In advanced electronics, a trimming capacitor is often used for initial setup and calibration. Once the optimal setting is found, it is typically not adjusted again during normal operation, unlike a variable capacitor which might be adjusted by the user.

Variants and Related Words

• Trimmer capacitor: A common synonym for trimming capacitor.
• Variable capacitor: A broader category of capacitors with adjustable capacitance, which includes trimming capacitors. A trimming capacitor is a type of variable capacitor designed for fine, infrequent adjustments.
• Capacitor: The general term for a component that stores electrical energy in an electric field.

Synonyms

• Trimmer
• Trimmer capacitor
• Adjustable capacitor (in the context of fine-tuning)

Related Technical Terms

• Tuning: The process of adjusting a circuit to a desired frequency, often using components like trimming capacitors.
• Calibration: The activity of checking and adjusting the precision of a measuring instrument or circuit, which is the primary function of a trimming capacitor.
• PCB (Printed Circuit Board): The platform on which a trimming capacitor is often mounted.

Noun

1. capacitor having variable capacitance; used for making fine adjustments
