Product details

Procurement of electronic components

Printed Circuit Board Assemblies (PCBAs) are composed of various electronic components, each serving specific functions essential to the performance of electronic devices. Below are some of the most common components found in PCBA:

1. Resistors

Function: Limit current flow and divide voltages.

Types: Fixed, variable (potentiometers), and surface-mount resistors.

2. Capacitors

Function: Store and release electrical energy, filter signals, and smooth out voltage fluctuations.

Types: Electrolytic, ceramic, and tantalum capacitors.

3. Inductors

Function: Store energy in a magnetic field, filter signals, and smooth current flow.

Types: Air core, ferrite core, and toroidal inductors.

4. Diodes

Function: Allow current to flow in one direction, protect circuits from voltage spikes (Zener diodes), and convert AC to DC (rectifier diodes).

Types: Standard, Zener, Schottky, and light-emitting diodes (LEDs).

5. Transistors

Function: Act as switches or amplifiers in electronic circuits.

Types: Bipolar Junction Transistors (BJTs) and Field-Effect Transistors (FETs).

6. Integrated Circuits (ICs)

Function: Combine multiple electronic functions into a single package, including microcontrollers, amplifiers, and logic gates.

Types: Analog ICs, digital ICs, and mixed-signal ICs.

7. Microcontrollers and Microprocessors

Function: Serve as the brain of the device, executing programmed instructions and controlling other components.

Characteristics: Include built-in memory and input/output interfaces.

8. Connectors

Function: Facilitate electrical connections between different components or devices.

Types: Header connectors, terminal blocks, and USB connectors.

9. Switches

Function: Control the flow of electricity in a circuit by opening or closing connections.

Types: Toggle switches, push-button switches, and DIP switches.

10. Sensors

Function: Detect environmental changes (temperature, light, motion) and convert them into electrical signals.

Types: Temperature sensors, accelerometers, and proximity sensors.

11. Power Supply Components

Function: Convert and regulate electrical power for the circuit.

Types: Voltage regulators, DC-DC converters, and power management ICs.

Conclusion

12. Oscillators

Function: Generate precise frequencies used in timing applications.

Types: Crystal oscillators and RC oscillators.
