ACT421LCSMX-4 (Preferred type)

The ACT421LCSMX-4is a 4 pad, high quality, low aging SMD Crystal in a ceramic base /

metal lid package, seam welded for good long term reliability. The lid is grounded through

the package to assist with EMI issues and the pads are gold plated. Its wide frequency

range and frequency tolerance / stability options with its small size make the device ideal for

many applications including Bluetooth, Notebook, PCMCIA, Instrumentation,

Microprocessor Systems and Wireless / Communications equipment.

Available loose or on 2K reels to suit high/low volume requirements.
