Compact Snap-in Aluminum Electrolytic Capacitors
TDK Corporation presents more compact versions within the B43640 and B43644 series of aluminum electrolytic capacitors with a snap-in design for rated voltages of 400V and 450V. In comparison with the previous versions they are up to 15 percent more compact. All types are suitable for a maximum operating temperature of 105 degrees C.
All versions of series B43640 are designed for a useful life of 2000 hours. They offer capacitances of between 120µF and 1000µF (400V), and between 82µF and 820µF (450V). Depending on the rated capacitance and voltage, the dimensions are within the standardized grid of between 22mm x 25mm and 35mm x 55mm (d x h).
The entire range of the B43644 series, on the other hand, has a useful life of 5000 hours. They cover capacitance ranges of between 100µF and 820µF (400V), or between 68µF and 680µF (450V). The dimensions of these types are within the standardized grid of between 22mm x 25mm and 35mm x 55mm (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.
