Note: For resonant resistance other than the standard values, they are specified by Fujitsu considering matching data with
applied IC (mainly micro computer).
■ 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.
