Every electronic device is a harmony of thousands of tiny elements. In this article, we take an in-depth look at the functions of the key components available in Artek's extensive warehouse.
1. Resistors: Restraining Current
A resistor is not just a resistor. Its power (Watt) and tolerance (Tolerance) are important.
- SMD and Through-hole: Modern thin devices use SMD (Surface Mount Device) resistors. Their sizes start from 0402 and require soldering under a microscope.
- Variable resistors (Potentiometers): Used to adjust sound level or light brightness.
2. Capacitors: Energy storage
Capacitors keep the voltage in the circuit stable and filter out noise.
- Electrolytic capacitors: Used where high capacitance is required (e.g. power supplies).
- Ceramic and Tantalum capacitors: Placed around microcircuits that require fast response.
3. Microcircuits (Integrated Circuits - IC)
Microcircuits are a combination of thousands of transistors on a single crystal. Microcircuits represented in Artek are divided into the following groups:
- Logic ICs: For processing digital signals.
- Microcontrollers: They are programmable "brains" (Arduino, STM32, etc.).
- Voltage regulators: Elements that provide a constant voltage.
