DESCRIPTION
Fujitsu resonators (C1, C3, C4 series) feature originally developed single crystals with a high electromechanical
coupling coefficient (LiTaO
3
: lithium tantalate, LiNbO
3
: lithium niobate), the result is compact packaging. Three
series are available: the C3 and C4 series with built-in capacitors for high integration, for exclusive use in
microcomputer clocks; and the C1 series for high precision. All series include the CHIP type device for surface-
mount and the SIP type device for general PC boards.

FEATURES

Surface-mount technology can be applied to the CHIP type to increase packaging density. The SIP type is
only half the height of conventional quartz crystal resonators, and can be easily mounted on general PC boards.
The C3 and C4 series have been developed for exclusive use in microcomputer clocks. They have built-in
capacitors, and the number of components has been reduced to one-third of that of conventional circuits.
Both the SIP and CHIP types can be shipped in taped packages for automatic mounting.
The resonators have superior shock and vibration resistance, preventing damage during automatic insertion
process.
