Passive Components

Passive components are elements of a circuit that do not perform any amplification or rectification function (usually referred to as resistors, capacitors, coils...), being necessary for every circuit. Solectroshop offers a wide range of passive components for both beginner and professional electronics hobbyists at all levels and prices.

  • Quartz crystals (oscillators)

    Quartz crystals are passive components which are used for stabilisation of current oscillations, e.g. created by electronic oscillators. The stabilisation effect is made possible by mechanical resonance. Due to their precision, quartz crystals have many applications in electrical and radio engineering. So in your projects you will mainly need them with radio wave controlled devices or frequency measuring devices. Quartz crystals are mainly characterised by their frequency which can vary from 3.5MHz up to 20MHz (in our offer).

  • Resistances

    Resistors are elements that introduce electrical resistance between two points in an electrical circuit. Resistors decrease the current flowing through a circuit. For a project, it is very important to understand the parameters of resistors - their maximum current and maximum potential difference, as exceeding these values can dissipate a lot of heat in the body of the resistor and the entire circuit. The most popular maximum power values are 0.25W, 0.5W and 1W. Check out our range of foolproof resistors and if you have any questions please refer to the forum or product page.

  • Polymer fuses

    Polymer fuses or resettable fuses - are components that protect your circuit against overloads. It is an ingenious invention - due to the polymer characteristic their resistance increases with the temperature corresponding to the current flowing through a circuit. So, in principle, polymer fuses work in a very similar way to thermistors. To learn more about the differences see our forum and tutorial section. The parameters that specify fuse performance are the operating current and operating voltage. Again, knowing the requirements for these parameters is crucial to avoid damaging your circuit. In our offer we have fuses from 60 to 90V voltage and from 100mA to 900mA current.

  • Capacitors

    Capacitors are devices capable of accumulating energy through the electric field. They are the basis of what we know today as batteries. The basic capacitor consists of two plates separated by a dielectric material or vacuum, so the conductive plates accumulate electrical energy that can be released during the discharge period. Electrolytic capacitors have polarised terminals and are therefore not suitable for alternating current (reverse polarisation destroys the oxide which short-circuits and burns the capacitor). Our offer includes both electrolytic and ceramic capacitors. The most important characteristics of capacitors are their capacitance measured in Farads, maximum voltage and maximum temperature in case of ceramic capacitors. Check our offer and materials on the page to learn more.

  • Potentiometers

    Potentiometers (or simply variable resistors) are resistors whose value can be adjusted manually. The characteristics you have to take into account are the same as with resistors. In our offer we have a wide range of potentiometers starting with the standard screwdriver knob potentiometers and sliding potentiometers up to horizontal potentiometers. For each of them we also offer trim knobs in different colours. Check our offer below

  • Inducers

    Inductors, also known as coils or reactors, are passive components that accumulate energy in the form of a magnetic field. Connected with the capacitor they create a resonant circuit (LC oscillator) - one of the most basic circuits in electronics. Inductors without a magnetic core are called solenoids and inductors stored by direct current are called electromagnets. Inductors are an important part of our offer. Please contact us with specific questions or requests.

  • Magnets

    This category includes all items related to the operation of magnetic magnets. For any application you need, in our offer you can find the perfect magnets for your project. Whether for access control, as part of a measuring device or as part of a robotic project.

  • Fuses

    A definition of fuses would be devices that are inserted at a certain point in an electrical installation so that they melt due to the Joule effect when a value of current intensity is exceeded.
