The package provides for the durability and reliability, necessary for reflow processes. The pads are gold plated. With its wide range of frequencies allowing for ease of circuit design, and with a good range of stabilities, it has become one of the optimum choices for design engineers. (Available loose or reeled to suit low / high volume requirements). Applications include Microprocessor Systems, Instrumentation, Communications, Notebook & PCMCIA and many more.

As each of these specification parameters impact on each other, it is not always possible to combine all options in one device. Therefore, if a specification not catered for above is required, please contact us directly for the relevant part number code(s). 2) ACT are always happy to consider truly custom specification parts which may require non-standard specification parameters, specific testing, customer requested AQL requirements, non standard packaging or taping and reeling and custom marking. Such devices would normally be allocated a custom specification part number which is wholly customer specific. ( MOQ dependent ) ( EG : A 12.00MHz custom ACT845SMX-4 device may have a part number such as AZ1200C- C2222PF) 3) Frequencies below 10.000MHz are prefixed with a "0" (eg: 0900 = 9MHz.Whereas 10.000MHz is 1000 ) ISO9001 Registered For quotations or further information please contact us at: 3 The Business Centre, Molly Millars Lane, Wokingham, Berkshire, RG41 2EY, United Kingdom http:www.actcrystals.com Issue 4 H2 Date 14/12/2010 Page 3 of 3
