Resonator

Piezoelectric Resonator (4 to 16 MHz)

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.

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.”)
• Frequency and standard resonant resistance
Frequency		Standard resonant resistance
4.00 to 5.99 MHz		150 Ω max. (Symbol: 1)
6.00 to 16.00 MHz		75 Ω max. (Symbol: 2)

■ 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.
