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.”)

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.
