What it represents
This representation distinguishes a differential capacitive arrangement with related variable capacitances. Related capacitor sections change in a coordinated differential arrangement. The common and section terminals therefore matter to interpreting the complete circuit.
Show those electrodes and the adjustment relationship in the detailed schematic. A single capacitance value or a two-terminal capacitor representation can hide the additional circuit interface.
How to read it
- Identify the electrode/common connections and the intended adjustment relationship.
- A differential capacitor is not a generic two-terminal fixed capacitor.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Identify the electrode/common connections and the intended adjustment relationship.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
A differential capacitor is not a generic two-terminal fixed capacitor.
