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 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 has become one of the optimum choices for design engineers. Applications include Communications, Microprocessor Systems, Instrumentation and particularly Wireless Communications applications. Available loose or on 1,000pc reels.
