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.

*: The capacity of the built-in capacitor is 20±8 pF by standard.
10±4 pF and 30±8 pF types are also available. However, the characteristics of 10±4 pF and 30±8 pF types are specified by
Fujitsu, considering matching data with applied IC (mainly microcomputer).

NOTES ON USE
•
•
Handle carefully.
Solder under the following conditions.
CHIP type: 5 seconds max. at 230°C (PCB)
SIP type: 10 seconds max. at 260°C
Do not apply extreme heat to the resonator. Recommended preheating for the CHIP type is 150°C for one
minute.
Avoid extreme fluctuations in temperature during use.
There is no specific direction in resonator mounting.
Additional information is available separately, if required, for designing microcomputer oscillation circuits.
CHIP type is for reflow solder, not for flow solder.
