The EPCOS B43706* and B43726* series aluminum electrolytic capacitors with screw terminals are designed for rated voltages between 400VDC and 500VDC and cover a capacitance range of 820µF to 15000µF.
A special feature is the high-rated current capability of up to 56.1AC (100 Hz, 85 °C). In case of standard operating conditions (for example, at 300Hz, 60 °C, 2 m/s), currents of up to 100A can even be reached. These values mean an approx. 25 percent increase in the current capability in the case of rated conditions in contrast to previous series.
The robust capacitors are designed for a service life of 12000 hours at +85°C. A precise service life calculation can be performed with the online AlCap Tool (www.tdk-electronics.tdk.com/en/alcap_tool). Similar to other EPCOS screw terminal series, a range of options such as heat sink mounting or special terminals are available as reverse polarity protection.
The new capacitors are particularly well suited to frequency converters and industrial power supplies as well as UPS systems. Furthermore, the capacitors can be effectively used for converters in the renewable energies sector, such as wind power and photovoltaic system.
