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 shop24.capcomp.de 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.

The quality of CAPCOMP's advice and sales performance is highly valued by our industrial customers. Your success is our success.

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 = SupercapsUltracapacitors = UltracapsGoldcap™ [Panasonic]Boostcap™ [Maxwell]Greencap™ [Samwha]PURIXEL™ [Pureechem] for supercap cellsPURETRON™ [Pureechem] for supercap modules

Z - Diodes

Z-diodes (formerly: Zener diode) are diodes that are designed to be operated permanently in the reverse direction in the breakdown voltage range. The level of this breakdown voltage UBR is the main characteristic of a Zener diode and is specified for the respective series or the individual article in the data sheet.

The diodes of the manufacturer NAINA Semiconductor consist of glass-passivated chips and are built in highly reliable, robust hermetically sealed package structures. They are mechanically strong and stable under negative environmental conditions.
These components have a very low forward voltage drop and a very fast switching function and thus a better efficiency. The very low forward voltage also reduces the power loss.

Use of Zener diodes

Zener diodes are used in various applications such as voltage clamp applications, photovoltaic solar systems, switching power supplies, rectifiers, detectors, motor drives, etc. We recommend the Z-diodes of the manufacturer NAINA, which can cover the following voltage ranges with its assortment.

Voltage range: 6.8V - 200V for 10W & 50W
Voltage range: 7.0V - 75V for 20W & 75W
Voltage range: 34.5V - 150V for 300W

Facts about Zener Diodes

In the past, these diodes were named after the American physicist Clarence Melvin Zener, the discoverer of the Zener effect (electrons tunnel through the junction). Since the 1970s, the name Z diode has been recommended because the Zener effect is only responsible for low breakdown voltages. In the forward direction, they behave like normal diodes. In the reverse direction, Z-diodes are reverse-biased at low voltages, just like normal diodes. Above a certain reverse voltage, the so-called breakdown voltage, the current increases by many orders of magnitude within a few hundred millivolts.
