Inductive components for power electronics

  • Differential Mode Chokes
  • Common Mode Chokes
  • High frequency transformers
  • Line filters

The technical design of inductors usually depends heavily on customer-specific require­ments. Because these are so different in almost any case we only commu­nicate data sheets and quotations in direct dialogue with our customers.

Who can place an Order with us?

All those who have registered a trade. We supply to large customers as well as medium-sized companies, small busi­nesses and engineering offices. Schools, colleges, univer­sities and public institu­tions are also provided with technical advice and supplies. Depen­ding on the purchase quantity and product, we grant staggered prices that can vary on a daily basis. Ask us for an indivi­dual offer.

Do I have to order online in the shop?

No, you are also welcome to request an individual offer. The ordering option at is particularly suitable for smaller quantities. The WEBSHOP is to be understood as an additional service offer where you can get a quick overview of availability, delivery times and prices. Furthermore, with its filter and search function, the shop also offers a quick overview of the different variants, designs, voltages, currents. Our stock in Freiberg am Neckar (South West of Germany) is well stocked for the common types. Provided that our suppliers accept it, special solutions are also offered here. In this case, we recommend that you ask us about delivery times.

What can you expect from CAPCOMP?

Why are components like ultracaps called different names?

The variety of terms is explained by the English-language terms commonly used in the electronics industry, which are often mixed with German terms or used synonymously. In some cases, manufacturers have also introduced artificial terms to better distinguish themselves from competitors. Here are the most important examples:

Double layer capacitors (DSK) are referred to synonymously as:

  • EDLC (Electric Double Layer Capacitor)
  • Supercapacitors = Supercaps
  • Ultracapacitors = Ultracaps
  • Goldcap™ [Panasonic]
  • Boostcap™  [Maxwell]
  • Greencap™  [Samwha]
  • PURIXEL™  [Pureechem] for supercap cells
  • PURETRON™  [Pureechem] for supercap modules
