Sprague-Goodman: Ceramic Dielectric Trimmer Capacitors: Plastic Encased Type: 6 mm

CERAMIC DIELECTRIC TRIMMER CAPACITORS

Engineering Bulletin SG-305

Plastic Encased Type: 6 mm

Available With or Without Membrane Adjust Cavity Seal

FEATURES

Low cost due to automated production and solderless touch contact construction.
Wide selection of capacitance ranges.
Color coded housings.
Double plastic housing provides improved protection against dust & contamination.
Rugged construction (working parts supported by metal structure, not just plastic).
Easy blind tuning (2 slots at 90° angle in adjust cavity - accepts cross-slotted tool).
Visual indication of maximum capacitance setting.
Membrane seal on adjust screw access face (optional) provides protection against contaminants (flux, solvents, etc.) during production.
