ACT845SMX-2

The

ACT845SMX-2

is a 2 pad, cost competitive ceramic packaged, glass sealed crystal. The package

provides for the durability and reliability, necessary for reflow processes. The pads are gold plated. With its

wide range of frequencies allowing for ease of circuit design, and with a good range of stabilities, it has

become one of the optimum choices for design engineers. (Available loose or reeled to suit low / high volume

requirements).

Applications

include Microprocessor Systems, Instrumentation, Communications, Notebook & PCMCIA and

many more.
