SMD Aluminium Capacitors for Consumer and Industrial Applications

Six new series of SMD aluminium electrolytic capacitors from EPCOS offer options with small case size, extended temperature operation, low ESR values and long operating life.



Aluminium electrolytic types are attractively priced alternatives to tantalum types. The B411xx devices cover a capacitance range from 0.1µF to 1500µF and are designed for voltages from 4VDC to 100VDC. Depending on the CV value, their case sizes vary between 4mm x 5.4mm and 10mm x 10mm (diameter x length).

The B41141 and B41142 series feature ESR values as low as 0.8Ω, suiting them for a variety of applications requiring low impedance or high ripple current. Both series operate within a wide temperature range of -55°C to +105°C. The B41141 devices offer 1000 hours load life at +105°C and voltage rating of 6.3VDC to 50VDC, while the B41142 provides an extended 3000 hour load life and a maximum operating voltage of 35V.

The B41112 and B41121 capacitors are miniature devices designed for space constrained applications. The B41112 range offers an extended 2000 hour load life, 4V to 100V voltage range and an operating temperature of -40°C to +85°C. The B41121 provides the standard 1000 hour load life over a wider temperature range of -40°C to +105°C and voltage range of 4V to 50V.

The B41115 and B41124 series are general purpose devices featuring 2000 hour load life and wide temperature ranges of -55°C to +85°C and -55°C to +105°C, respectively.

All the new devices are RoHS compatible and suitable for applications in consumer and industrial electronics. To assist in selection and specification, EPCOS provides comprehensive product details in its new Alu-X® 2008 data book. In addition, more than 5000 competitor ordering codes for SMD aluminium electrolytic capacitors have been added to the company’s online cross-reference database to facilitate the search for EPCOS types.
