TDK Corporation announce two series of EPCOS aluminum electrolytic capacitors in extremely compact snap-in designs. The dimensions of the new B43640* and B43644* series are 22 x 25 mm to 35 x 55 mm, depending on the type. Thus, both series are significantly more compact than previous series for identical rated voltage and capacitance values. Moreover, both series feature very high ripple current capability.

The B43640* series is designed for rated voltages from 200 V DC to 450 V DC and covers a capacitance range from 82 μF to 3300 μF. At a continuous operating temperature of 105 °C, these capacitors attain a service life of 2000 hours. The B43644* series is suitable for rated voltages from 200 V DC to 500 V DC and is available with capacitance values from 39 μF to 2700 μF. These capacitors reach a service life of 5000 hours at a continuous operating temperature of 105 °C.

Thanks to their more compact dimensions, these new snap-in capacitors are suited as link circuit capacitors in compact frequency converters, solar inverters and power supplies for industrial applications.
