Passive elements

Passive components - electronic Components, passive (passive) are the components of electronic systems that do not produce electrical current. This group can be attributed, among other things, resistors (resistors), capacitors, inductors, variable resistors and resonators. The proposal is, as passive elements, made in the SMD technology (surface) and TNT (przewlekanej). Also available special packages for people who only collect materials to create projects, electronic, or want to add to my collection.

Passive elements

In the proposal we have passive elements with various parameters. We offer, in particular:

  • Fuses the elements that have the task to stop the flow of current in the circuit exceeding the specified value of this parameter (usually voltage). The proposal can be found, in particular, polymer fuses, i.e., such that when exceeding a certain value of voltage to heat up and open the circuit. This type of fuse can even be used about 100 times (it should, however, know that an open circuit is never perfect, and too high voltage can cause breakdown and eventually damage the circuit elements). Also available automotive fuses, a fuses, which constitute the essential elements of the power network in vehicles internal combustion engines. They are disposable - when exceeding this value the intensity topik remains molten, and the circuit is interrupted forever. In offer we also have fuses, overcurrent, thermal fuses (temperature from 96° C to 135° C) fuses WTA if the connectors of the fuses.
  • Crystals: electronic components, which have the task to stabilize the frequency of oscillations of electronic. This property is used for example for the manufacture of watches, stopwatches, electronic or pilots using a radio signal. The frequency of these elements varies from several tens kHz to tens or even hundreds of MHz in the range of approximately resonators from 32 kHz to 16 MHz (elements of SMD and THT).
  • Resistors (resistors): the easiest and most popular element of most passive electronic circuits. It is used to regulate the voltage to the needs of the device (the resistor is stopped turns the energy into heat). Working linear voltage drop is directly proportional to the intensity of the current passing through the resistor. We have a coal resistors resistance values from 0.1? to 1.5 M?, heating resistors, resistors made of THT, SMD (0805 and 1206) and sets of resistors.
  • Potentiometers: adjustable voltage dividers that act as resistors with adjustable resistance in the specified range (often called a potentiometer resistor adjustable). The range of the potentiometers on opornościach from about 1 k? up to 500 k?, including zip potentiometers, rotary actuators, precision, digital (small chip), touch of the SMD and THT, with switch, with connector trzyżyłowym, sets of potentiometers (in the diary). There are handles for easy control with a potentiometer.
  • Capacitors: passive elements consist of two plates of conductors separated by a dielectric. We have in stock, ceramic capacitors and electrolytic, Low ESR, tantalum and motor. The electrolytic and ceramic capacitors are available in both versions przewlekanej (TNT), as on the surface (SMD).
  • Chokes: the type of coils that are often used as filtering elements the transmitted signal. We have components with inductance values from 4.7 mH hic 1 and the various opornościach and the degree of intensity.

Kits electronic components

The range of practical sets of passive elements. If you are a beginner or need to augment and better organize existing components, perfect sets, organizerach. Available kits specific elements with different parameters (for example, bipolar transistors, resistors or capacitors), as well as more diverse sets (e.g., contact plate, sets of wires, resistors, LEDs, a power source for circuit boards, transistors, capacitors and much more). Especially popular are specially prepared sets for free courses from the portal FORBOT.
