Tel : Fax : email : ACT HC49/US-SMX 0044 (0)118 979 1238 0044 (0)118 979 1283 [email protected] (Custom Packages) The ACT HC49/US-SMX is one of the most cost effective and popular surface mount crystals available. With it’s wide range of frequencies, stabilities and operating temperatures it is still small enough to fit most applications including many hand held units and is the economical solution for automatic assembly. With it's available tight tolerances / stabilities and available operating temperature ranges, the HC49/US-SMX is a favoured choice in many applications, including Communications, Industrial Controls, Microprocessor Systems, Vending, Security and Access Control.

As each of these specification parameters impact on others, 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. ( EG : A 12.00MHz custom ACT49/USMX device may have a part number such as PO1200C- C1246-PF) 3) Frequencies below 10.000MHz are prefixed with a "0" (eg: 0800MHz = 8MHz.Whereas 10.000MHz is 1000 and a frequency of 100MHz is 10000.).
