IEC

Split adjustable capacitor

This representation distinguishes the publisher's split and adjustable capacitor form. More than one capacitive section belongs to the publisher’s split adjustable form. The section/common relationships and the coordinated adjustment are part of the circuit interpretation.

A distinction that matters

Multiple capacitive sections must not be collapsed into a single unqualified capacitance value.

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.

A distinction that matters

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