Tab and cover terminations are flangeless devices with protective ceramic covers and tab contacts, offering the highest performance available of any style of component. They are designed for direct solder
attachment to a heat sink or circuit board (thermal vias required) for excellent heat transfer. These devices deliver excellent VSWR over a broad frequency band. The frequency ranges from DC to 18 GHz. The power rating ranges from 10 to 500 watts. Optional lead forming
is available on most designs.

Suggested mounting procedures:
1.Solder part or tabs in place with controlled temperature iron (260℃)
2.Forming a small loop in the tab will act as a strain relief as the heat is dissipated.
