ECL series

Vishay Intertechnology Inc. has released a new series of surface-mount aluminum capacitors that offers high-temperature operation +105C, low impedance values and high capacitances and ripple currents.

Designed for surface mounting on high-density PCBs, the new ECL series of polarized aluminum electrolytic capacitors features a non-solid, self-healing electrolyte. For high-temperature operation, a heat-resistant pad and molded base plate provide additional stability and protection.

Available in six case sizes, ranging from 6.3mm x 5.80mm to the larger 12.5mm x 13.5mm, the devices are optimized for inverter circuits and filtering, smoothing and buffering applications in industrial systems and consumer electronics, such as audio equipment, flashes, and computers.

For enhanced performance and reliability, the capacitors offer a very low impedance Z down to 90m? at 100kHz, a high rated ripple current of 670mA at +105C, and a capacitance range from 10?F to 1500?F over a voltage range of 6.3V to 100V.

Specified according to IEC 60384-4/EN 130300, the ECL devices feature a long life of 2,000 hours at +105C. Supplied in blister tape-on-reel packaging, the RoHS-compliant capacitors are compatible with reflow soldering and automatic insertion machines.

Samples and production quantities of the new ECL series are available now.
