AXIAL LONG LIFE CAPACITORS
New cubic design for axial electrolytic capacitors
Axial aluminium electrolytic capacitors are normally cup-shaped – the Husum-based capacitor expert FTCAP demonstrates, however, that this does not necessarily have to be the case: the new cubic design offers significant advantages especially with respect to cooling.
“Generally, the capacitors are in contact with the cooling modules. The larger the contact surface, the more effective the cooling,” explains Dr. Thomas Ebel, Managing Director of FTCAP. “Compared to the traditional designs, capacitors with the new design have a 28 % larger surface.” This larger contact surface allows better connection of the cube-shaped capacitors to the cooling systems, which results in improved cooling capacity. That, in turn, results in significantly better current-carrying capacity – this design allows it to be duplicated. The hermetic laser sealing of the cover also makes it possible to double the service life. Another advantage of the cubic design is the high degree of space utilisation: the capacitors are designed for flat mounting and can even be stacked. With dimensions from 10x10x20 mm to 18x18x49 mm and voltages from 25 to 100 volts they are ideal especially for use in the automotive industry. The capacitors are designed for combination in a modular system and the capacities can be adjusted individually. The innovative components feature internal multiple contacts with up to four lugs.
Dr. Thomas Ebel, Managing Director of FTCAP, uses this short video to explain the advantages of the new, cubic design for axial capacitors.
LONG LIFE CAPACITORS
Aluminium electrolytic capacitors for extreme conditions!
New technology is now being used to manufacture high-precision rectangular capacitors in Husum.
The hermetically sealed component guarantees a long life due to a laser-welded cover. Also, the rectangular design promises a better cooling capability. This space-saving design with flat windings has potential for diverse applications.

This makes mounting of different levels easier and less expensive, since no additional spacer is needed; in addition, it guarantees a solid and secure connection. The same screws can be used for both terminals, since they have the same thread depth.
Since FTCAP manufactures the terminals in-house, any desired height is possible – at the price of standard terminals. The terminals can be designed with female threads or male threads.

A third connection terminal opens up new areas of application for the customer. This makes it possible to use the two single capacities in series, for example, to double the dielectric strength, or in parallel to double the capacity with twice the current-carrying capacity and half the series resistance (ESR). The two internal single capacitors are symmetrical and always have the same properties, due to the identical design.

Rethinking invertes assemblies!
In another project, a customer chose to create a capacitor modul by using affordable Snapincapacitors in a series/parallel configuration across a printed circuit board.
In spite of all efforts made, the capacitors in this particular device could only offer a 2year lifetime because of the extremely harsh environment. The replacement costs interms of technicians time and labor were enormous. So the customer decided toreduce his overall maintenance and repair costs by removing the old capacitors (de-solderingthem one-by-one) and then replacing them with one simple, easy-to-install FischerLink.
In this particular example, the FischerLink was delivered with heat-transferpads to optimize even more the dissipation of the heat. In the end, the customer is alsobenefitting from longer lifetimes, further reducing his maintenance costs!
In the customer’s original design, the current had to be limited because of the thickness ofthe copper plates. The FischerLink solution was designed with bus-bar that withstands significantly higher levels of current.
