Schematic symbol terminals, also known as pins or connectors, are the small metal contacts that appear on a schematic symbol of an electronic component. These terminals are used to represent the electrical connections between components in a circuit diagram or schematic.

Each terminal on a schematic symbol corresponds to a physical pin on the actual component. For example, a resistor symbol may have two terminals, which represent the two leads of the resistor. The terminals are usually labeled with letters, numbers, or other symbols that indicate the function or purpose of the connection.

When designing a circuit, the schematic symbol terminals are used to show how the component is connected to other components in the circuit. For example, the terminal on a transistor symbol that represents the emitter might be connected to the ground, while the collector terminal might be connected to the power supply.

It is important to correctly label the terminals on a schematic symbol, as this ensures that the circuit diagram accurately represents the physical connections of the components in the actual circuit.
