ISELIN, NJ--(Marketwired - Sep 13, 2016) - TDK Corporation today announced more compact versions within the EPCOS B43640* and EPCOS B43644* series of aluminum electrolytic capacitors. The series features a snap-in design for rated voltages of 400 V and 450 V. The new versions are up to 15 percent more compact than previous versions. All types are suitable for a maximum operating temperature of 105°C.
All versions of series B43640* are designed for a useful life of 2,000 hours. They offer capacitances of between 120 µF and 1000 µF (400 V), and between 82 µF and 820 µF (450 V). Depending on the rated capacitance and voltage, the dimensions are within the standardized grid of between 22 mm x 25 mm and 35 mm x 55 mm (d x h).
The entire range of the B43644* series, on the other hand, has a useful life of 5,000 hours. They cover capacitance ranges of between 100 µF and 820 µF (400 V), or between 68 µF and 680 µF (450 V). The dimensions of these types are within the standardized grid of between 22 mm x 25 mm and 35 mm x 55 mm (d x h).
The new capacitors are suitable, among other things, for the use in converters, power supplies and household appliances. In order to calculate the precise useful life of aluminum electrolytic capacitors, the use of the web-based EPCOS AlCap Useful Life Calculation Tool is recommended.
