ACT2016SMX-4

The ACT2016SMX-4 is an extremely compact, high quality, low aging, seam welded crystal. Utilising a

ceramic base with a metal lid, it provides for the durability and reliability, necessary for strenuous

processes like infrared and vapour reflow. The lid is grounded through the package, to assist with EMC

Issues, and the pads are gold plated. The device is very suitable for automatic placement on PCB's.

With an excellent range of frequencies and stabilities it is an optimum choice for designs where PCB

space is at a premium. Applications include: PDA, Cellular, MPU Clocks, ISM, Bluetooth, WLan, and

consummer electronics. Available loose or on reels (Standard 3,000 pieces / reel.).
