With the widespread use of micro electronic products, the size of electronic components is getting smaller and smaller. SMT chip components are divided into three categories according to their functions: passive components, active components and electromechanical components.

Passive components: resistors—thick film resistors, thin film resistors, thermal devices, potentiometers, etc.

Capacitors–multilayer ceramic capacitors, organic film capacitors, mica capacitors, chip tantalum capacitors, etc.

Inductors–multilayer inductors, wirewound inductors, chip transformers, etc.

Composite devices – resistor networks, capacitor networks, filters, etc.

Active devices: discrete components – diodes, transistors, crystal oscillators, etc.

Integrated circuits-chip integrated circuits, large-scale integrated circuits, etc.

Electromechanical period: switches, relays – toggle switches, tact switches, reed relays, etc.

Connectors – chip jumpers, cylindrical jumpers, plug-in connectors, etc.

Micromotors – micro micromotors, etc.
