IEC

Differential capacitor

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.

Drawing use: Schematic
Application: Electronic components
Reference family: IEC / Manufacturer
Form evidence: Differential capacitor. Autodesk IEC-60617 Symbol Preview — Capacitive component forms; vendor family reference, not certified IEC geometry or database identifier.

A distinction that matters

A differential capacitor is not a generic two-terminal fixed capacitor.

Resistor

A resistor representation identifies a resistive component in a circuit. Different drawing conventions can use different basic outlines, while additional qualifiers distinguish variable resistors, shunts or heating elements. The value, rating and purpose are separate annotations.

Drawing use: Schematic
Application: Control circuits
Reference family: IEC / IEEE / ANSI

A distinction that matters

IEC-style rectangular and other conventional resistor depictions can describe the same component concept, but qualifiers and documentation still matter.
