Electrolytic capacitors rated for voltages between 400 VDC and 500 VDC
TDK’s EPCOS aluminium electrolytic capacitors B43706 and B43726 series with screw terminals are available at distributor Digi-Key.
These components are designed for rated voltages between 400 VDC and 500 VDC and cover a capacitance range of 820 µF to 15,000 µF.
A special feature is the high-rated current capability of up to 56.1 AAC (100 Hz, +85°C). In standard operating conditions (for example, at 300 Hz, +60°C, 2 m/s), currents of up to 100 A can be reached.
These values mean an approximate 25% increase in the current capability under rated conditions in contrast to previous series.
The robust capacitors are designed for a service life of 12,000 hours at +85°C.
Similar to other EPCOS screw terminal series, a range of options such as heatsink mounting or special terminals are available as reverse polarity protection.
Applications cover industrial frequency converters, UPS systems, wind power and photovoltaic systems.
