Ø7.5 mm Film Dielectric Trimmers

Transcription

1 Vishay BCcomponents Ø7.5 mm Film Dielectric Trimmers FEATUES Housing diameter 7.5 mm For a basic grid of 2.54 mm (.1") or 2.5 mm Top and bottom or top adjustment Vertical and horizontal versions ound or hexagonal head APPLICATIONS For consumer and industrial equipment DESCIPTION: The vanes of the trimmer are stacked on a sturdy plastic base. The color of the base indicates the maximum capacitance (see Electrical Data Table). The dielectric is a film of polypropylene (PP), polyethylene (PE), polycarbonate (PC), polytetrafluorethylene (PTFE), or polyethyleneterephtalate (PET) which supports the vanes in such a way that good stability is ensured and no microphony can occur. Flux absorption between the vanes is prevented. Cleaning with solvents is not advised. Versions are available with either a vertical spindle, or a horizontal spindle (see dimensional outlines). Both versions have top adjustment by means of a screwdriver or trimming key and bottom adjustment by means of a key.
