## Symbol convention

Convention: IEC
Form: Preset-adjustable capacitor
Autodesk IEC-60617 Symbol Preview — Capacitive component forms; vendor family reference, not certified IEC geometry or database identifier.

This form distinguishes a capacitor with a preset or trim adjustment.

## What it represents

This form distinguishes a capacitor with a preset or trim adjustment. A trim or preset adjustment sets the capacitive value for the documented circuit function. The setting interface is different from a continuous operator adjustment in ordinary use.
Identify the adjustment function and the circuit terminals. The component value, range and setting method belong in the equipment or component documentation.

## How to read it

- State how the capacitance setting is specified and which terminals belong to the device.
- A preset adjustment is different from an operator-controlled variable capacitor.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- State how the capacitance setting is specified and which terminals belong to the device.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

A preset adjustment is different from an operator-controlled variable capacitor.
