Aluminum electrolytic capacitors: SMD series for consumer and industrial electronics

No picture available

The new SMD aluminum electrolytic capacitors from EPCOS cover a capacitance range from 0.1 µF to 1500 µF and are designed for voltages from 4 V DC to 100 V DC. Versions are available for temperature ranges from -40 °C to +85 °C and from -40 °C to +105 °C. Depending on the CV value, the case sizes vary between 4 mm x 5.4 mm and 10 mm x 10 mm (d x l). The B41142* series with ESR values from a minimum of 0.8 Ω is particularly suitable for applications requiring high ripple current capability. The operating life of the capacitors of this series is 3000 hours (105 °C). All types are RoHS-compatible. The new capacitors are suitable for applications in consumer and industrial electronics. They are an attractively priced alternative to tantalum capacitors.

The updated range is shown in the new Alu-X® 2008 Data Book (ordering code

EPC:27017-7600). In addition, more than 5000 competitor ordering codes for SMD aluminum electrolytic capacitors have been added to the X-Reference database ( in order to facilitate the search for EPCOS types.
