This series is much more compact than other versions available in the market, results competitive in terms of capacitance per unit of volume even when compared to electrolytic designs together with other parameters (Capacitance stability, life time, etc,…).

EPCOS presents a wide range of capacitances and voltages going up to 110 mF in a maximum volume of 35x50x57.5mm3. Typical industrial applications where DC-Link capacitors play an important roll are uninterruptible Power Supplies (UPS), switch-mode power supplies (SMPS), and more generally inverters such as the solar inverter in the most recent years.

EPCOS released the B3267*P* series which has a significantly reduced volume.  The new series comprises types with lead spacings of 10 mm, 15 mm and 22.5 mm, respectively. The capacitors are designed for rated voltages of 450 V DC, 520 V DC and 630 V DC and cover a capacitance range from 68 nF to 2.2 μF. These components are suitable for a continuous operating temperature of 125 °C. The plastic of the case satisfies UL 94 V-0 specifications. Halogen-free versions are also available upon request.
