Specification

ACT200B and ACT200C

The ACT200B and ACT200C are miniature SMD Watch Crystals 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. Both parts are RoHS compatiblethe ACT200C being Lead free and the 200B having high melting point

tin lead solder exempted by the directive.

Applications include: Clock, Sub Clock, Small Communications Devices, Microcomputer etc.
