Resonator

Piezoelectric Resonator (4 to 23.9 MHz)

FAR Family (C4 series N type)

■DESCRIPTION

Fujitsu resonators C4 series (N type) feature originally developed single crystals with a high electro-mechanical

coefficient (LiNbO3: lithium niobate), the result is very compact packaging.

C4 series (N type) with built-in capacitors f or exclusiv e use in microcomputer cloc ks , and this series is ultra low

profile CHIP type device for surface-mount (SMT).

■FEATURES

• Ultra low profile H = 1.6 mm

• Direct oscillation in 4 to 23.9 MHz frequency.

• Suitable for the source of microcomputer clock

• Emboss-typed pack for automatic mounting

• Superior shock and vibration resistance, preventing damage during automatic mounting

■STANDARD FREQUENCY

Notes: • Fujitsu can also develop applicable device in addition to standard devices if it’s oscillation frequency is

from 4 to 23.9 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

Note: Resonant resistance of custom designed part should be specified considering matching condition with

applicable IC by Fujitsu.

■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 micon or other ICs.

• This is for reflow solder, not for flow solder.
