Informace close
Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

Thanks to a wide assortment of products from the category of capacitors and also other passive elements (capacitors, resistors, fuses, filters), we’re a reliable supplier on the industrial market.

In the category of capacitors we deliver: capacitors for engines, electrolytic capacitors, capacitors snubber type, co-axial capacitors, ICEL folic capacitors, and power capacitors.

Regardless of whether you’re buying single products or in huge numbers, we offer full-service delivery. In our offer we deliver products from most reliable suppliers and which went through strict safety tests. Our goal is to provide high quality products and services to all clients.

What is a capacitor?

Capacitor is an electronic element composed of two conductors (lining) divided with a dielectric. Transferring the voltage to the lining of a capacitor causes electric charge condensation. We have aluminum, mika and folic electrolytic capacitors.

Basic parameters of capacitors:

Capacity C [F] – a unit of capacity is Farad [F], in practice smaller units are used, i.e.: mF (10-3 F), µF (10-6 F), nF (10-9 F), pF (10-12 F). Capacity is provided with an allowed tolerance.

Rated voltage Un [V] – max voltage value, which can occur on a capacitor in a continuous way without changing its characteristics. Due to a huge diversity of capacitors’ types, rated voltage can be a continuous voltage, alternating, with a given frequency, or pulse.

Substitute series resistance ESR [Ω] – represents entire losses in a capacitor, which  except series resistance of channeling and Rs electrodes, concerning losses in a dielectric, occuring during being affected by the alternating electric field.

Series substitute induction ESL [H] – concerning induction channeling and capacitor’s electrodes.

Rated current In [A] – max effective current value, which can flow through a capacitor in a continuous way.

In terms of a dielectric type, we can divide capacitors into the following groups:

Aluminum electrolytic capacitor – in a capacitor of this type, dielectrics are aluminum oxides with thickness depending on a rated voltage of a capacitor. Channels of electrolytic capacitors are marked and should be connected with a DC source by a positive electrode to a plus pole, and negative electrode to minul pole. The biggest advantage of electrolytic capacitors is a possibility to acquire a big capacitor’s capacity in proportion to its sizes. It's possible thanks to a huge surface of electrodes and using dielectric with small thickness. The range of rated capacities in the offered capacitors equals from 33 µF to 220 000 µF, and rated voltages from 10V to 500V. These capacitors can be applied in electronic devices.  Capacitors for industrial use are a special type of capacitors. These capacitors, thanks to a special construction of electrodes, have small series resistance and impendation values, which allows for acquiring huge current ripples. The range of rated capacities is from 100 µF to 1 500 000 µF, and alternating voltages from 10 V to 500 V. This type of condensators can be used in power electronics, e.g. UPS, inverters, pulse power supplies.

Mika capacitor – has a construction similar to ceramic capacitor, but due to a different production process it can also silver electrodes. Mika's capacitors are characterized by big insulation resistance, small losses and big stability of parameters. Capacities of offeter capacitors are placed from 51 pF to 0,51 µF, and voltages from 250 V to 15 kV. Because of their characteristics, they’re used mainly in high frequency systems.

Folic capacitor – a capacitor with a dielectric made of plastics – most often made from polypropylene, metal polypropylene or polyester. Capacitors with a dielectric made of plastics characterized by small losses, which comes from small resistance of electrodes and bug resistance insulation. In these capacitors it is possible to achieve big currents (up to several thousands of Amperes) and rated voltages (up to several dozens of thousands of volts), which allows for using them in power electronic systems as commutation, extinguishing and filtering capacitors for induction heating and high-voltage systems.
