C ELEC
Electrolytic capacitor
An electrolytic capacitor has a specified capacitance, voltage rating and any documented polarity requirement.

What it represents
The electrolytic capacitor form adds a documented construction or polarity qualifier to the capacitive function. The actual component determines whether polarity marking is required; this original preview illustrates a polarised use rather than declaring every electrolytic type identical.
This is a convention-specific lookup based on the publisher's IEEE-labelled preview. The geometry here is independently drawn to explain the connection or operation; it is not a certified reproduction of the standard graphic.
How to read it
- Check component polarity and allowed voltage before following the DC connection.
- Read the selected library and the project legend together. A vendor block identifier is meaningful within its named library and is not a universal standard-symbol code.
Information to show or reference
- State capacitance/voltage
- Preserve documented polarity
- Reference component type
A distinction that matters
Electrolytic construction is different from simply rotating a generic capacitor graphic.
