Ultra miniature watch crystal

IQD’s latest watch crystal design is one of the smallest in the world. Launching at Electronica 2010, the 32.768kHz IQXC-25 measures just 2.00 x1.2 x 0.6mm making it ideal when PCB real estate is at a premium. The ceramic package is a 2-pad device with an operating temperature range of -40 to +85°C and for which solder pad and layout recommendations can be provided. The crystal has a standard temperature coefficient of −0.03 +/-0.01ppm/degrees C2.

While frequently taken for granted, the humble watch crystal is fundamental to the function of millions of diverse products, from space satellites to washing machines. Its position as the lowest cost quartz crystal belies its importance in the modern world.

It is eminently suitable for all portable applications where accurate time keeping and non-volatile data storage is required via a Real Time Clock e.g. R.F.I.D, Metering, Security & Access Control, POS Terminals.

Available with an initial adjustment tolerance of +/-20ppm and a standard load capacitance of 12.5pF the IQXC-25 is also available for those applications that require a 9.0pF load. The product comes on Tape and Reel although for prototyping it is also available in bulk packaging.

Further details will be available at IQD’s stand 215 in Hall B5 at Electronica 2010.
