ACT200A - Prefered Product.
The
ACT200A
is a miniature SMD Watch Crystal with excellent low power consumption, making it ideal for
portable applications. Its small footprint makes it suitable for high density circuit boards and applications where
PCB space is limited. The tape and reel packaging means that it is ideal for automatic placement machines
(loose product is also available).
The heart of the device is a heat resistant precision tuning fork, cylinder type, crystal which provides for good
stability characteristics, sufficient to allow reflow soldering.
Applications include: Clock, Sub Clock, Small Communications Devices, Microcomputer etc.

SOLDERING of SMD WATCH CRYSTALS
Reflow oven should be set up to emulate or better the maximum reflow profile shown in the diagram below. Note it is just as
important to conform to the times given as well as the temperatures.

NOTES :
1)
Other Tolerances, CL's and other Operating Temperature Ranges may be available.
2)
ACT are always happy to consider truly custom specification parts which may require non-standard specification parameters,
specific testing, customer requested AQL requirements, non standard packaging or taping and reeling and custom marking. (
MOQ DEPENDENT ) Such devices would normally be allocated a custom specification ( An ACT200A device may have a part
number such as EK00003C- C1101-PF)
3)
Stability Over Operating Temperature (ºC) please refer to the data.
