Elektronikkdelen

Elektronikkdelen is a basic building block of electronic circuits. The term, used in Scandinavian languages, designates any discrete component that influences electrical behavior. Electronic components are chosen for their electrical characteristics, tolerance, power rating, and physical size, and they are assembled on printed circuit boards to form functional devices.

Components fall into broad classes. Passive components such as resistors, capacitors, and inductors do not amplify signals; they store energy, shape currents and voltages, or filter noise. Active components such as diodes, transistors, and integrated circuits can control energy flow or amplify and process signals.

Packaging and form factors vary. Through-hole components mount with leads that pass through PCB holes, while surface-mount devices (SMD) are soldered directly onto copper pads. Common small-footprint categories include resistors and capacitors in SMD sizes such as 0805 or 0603, and integrated circuits in packaging types like QFN or SOP.

In design, each component receives a reference designator on schematics and boards (R for resistor, C for capacitor, Q for transistor). Values and tolerances are specified in the bill of materials and datasheets. Prototyping and production often require manufacturers’ datasheets to ensure voltage, current, and thermal limits are not exceeded.

Quality and sourcing: electronic components are manufactured to defined electrical specifications and are rated for temperature ranges, tolerance, and reliability. They are sourced from distributors and manufacturers, with provenance and lot history tracked for quality control and repair.
