A Long Life Cubic Design and Hermetically Sealed For Extreme Conditions the FTCAP bring unique cubic design and ruggedized housings. These two aluminum electrolytic capacitors are a lesson in nonconformity to bring its advantage not limited to special applications.
A Long Life Cubic Design
FTCAP proves that cylindrical is not the only option when it comes to packaging an axial leaded electrolytic capacitor; this unique cubic design offers significant advantages with respect to component cooling due to the larger surface area in contact with the cooling system.
Aluminium electrolytic capacitors with a cubic design offer significant advantages especially with respect to cooling. Compared to cylindrical/round capacitors, they are also easier to stack, for more efficient space utilisation.
Compared to the traditional designs, axial aluminium electrolytic capacitors with the innovative cubic design have a 28 % larger surface. This large contact surface has positive effects on cooling, since in some applications the capacitors are mounted directly on the cooling modules. “This larger contact surface allows better connection of the cube-shaped capacitors to the cooling systems, which results in improved cooling capacity,” explains Dr. Thomas Ebel, Managing Director of FTCAP. “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 of aluminium electrolytic capacitors is the high degree of space utilisation: the capacitors are designed for flat mounting and can even be stacked. Dimensions between 10x10x20 mm and 18x18x49 mm and voltages of 25 to 100 volts make them ideal 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.
Hermetically Sealed For Extreme Conditions
Aluminium electrolytic capacitors for extreme conditions! 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 radial leaded aluminum electrolytic capacitor features a rectangular design and a laser-welded cover for long life operation in extreme conditions. The new energy storage design with its box design is perfectly constructed for radar applications, switch mode power supplies in aeronautics, impulse current applications in military and telecommunication. It supplies up to 6 joules of energy at dimensions of 16x35x35mm and has double the service life compare to the standard products. To improve heat dissipation it can be supplied with a heat sink. New technology is now being used to manufacture high-precision rectangular capacitors in Husum.
