It utilises a ceramic base and metal lid for durability. the lid is grounded through the package and the pads are gold plated. With a wide frequency range, and tight stability it has become one of the optimum choices for design engineers. Applications include Communications, Microprocessor Systems, Instrumentation and many more.
