FAR Family (C4 series P/Q type)
For Motor Application
DESCRIPTION
■
Fujitsu resonators C4 series (P/Q type) feature single crystals with a high electro-mechanical coefficient (LiNbO3:
lithium niobate), the result is very compact packaging.
DS07-10204-1E
(4 to 16 MHz)
C4 series (P/Q type) with built-in capacitors for exclusive use in microcomputer clocks, and this series is chip
type device for surface-mount and suitable for motor appication due to its high reliability package.
FEATURES
■
• Wide frequency range in 4 to 16 MHz
• Suitable for microcomputer clock
•PCT (121 °C, 2 atms, 96 hours) is guaranteed for Motor application.
• Emboss-typed pack for automatic mounting
• Superior shock and vibration resistance, preventing damage during automatic mounting

Notes:
■
• Fujitsu can also develop applicable device in addition to standard devices if it’s oscillation frequency is
from 4 to 16 MHz.
• Resonant resistance of the part other than standard, Fujitsu should specify its resonant resistance
according to applied frequency. (See “• Frequency and standard resonant resistance.”)

NOTES ON USE
• Handle carefully
• Solder under the following conditions.
5 seconds max. at 230°C (PCB)
Recommended preheating is 150°C for one minute in order not to apply extreme heat to the resonator.
• Avoid extreme fluctuations in temperature.
• There is no specific direction in resonator mounting.
• Oscillation data should be examined when used in oscillation circuit with microcomputer or other ICs.
• This is for reflow solder, not for flow solder.
