  Tab & Cover Attenuators
  Mounting: Solder
Tab and Cover devices are flangeless 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. The tab and cover attenuators have attenuation range from 1 dB to 30 dB. The attenuation tolerance for values between 1-10 db is +/- 0.5 dB and 11-30 dB is +/- 1.0 dB. All device are made compliant to RoHS.
