6 Text Tab and Cover Tab & Cover components are flangeless devices with protective ceramic covers and tab contacts, offering the highest performance available of any package style component. They are designed for direct solder attachment to a heat sink for excellent heat transfer. Tab & Cover attenuators have an attenuator range from 1 db to 30 db. The attenuation tolerance for values between 1-10 db is ± 0.5 db and db ± 1.0 db. Optional lead forming is available on request.
