They are suitable for portable equipment and where a close packing density is required.Two versions are offered, C1BLC: a low cost version and the HQM4E: a version with a higher Q value. The 1x5 device is only available in the High Q version.

The device should ideally be upright on the board. If the device can is required to be mechanically affixed to the board it should be stuck down with rubber adhesive. Under no circumstances should any solder connection be made to the can of the device. Please note that all parameters can not necessarily be specified in the same device Customer To specify : Frequency Tolerance, Load Capacitance, Operating Temperature Range In line with our ongoing policy of product evolvement and improvement, the above specification may be subject to change without notice ISO9001:2000 Registered For quotations or further information please contact us at: 3 The Business Centre, Molly Millars Lane, Wokingham, Berkshire, RG41 2EY, UK http://www.actcrystals.com Issue : 7C1b/M4E Date :03-10-07
