Tiny FC-255 crystal now available in UK

Epson’s tiny FC-255 crystal is now available in the UK from Hero Electronics. With the ceramic package measuring 5.0 by 2.0 by 0.9mm, the crystal has a low profile which suits it to use in applications such as portable equipment and cellular phones.

The miniaturisation has come via the use of a small tuning fork crystal combined with a new coating technology for the electrodes. This technology increases reliability and reduces the danger of electrode shorting.

The standard frequency is 32.768kHz, which is used in many clock and micro-controller designs. Custom frequencies can be made to specification. The operational temperature range is -40 degrees C to +85 degrees C, and the accuracy can be specified at either +/-20ppm or +/-50ppm.
