The SGNM trimmer capacitor is constructed with a high-purity ceramic dielectric–a fairly new development for trimmers that, according to the company, increase performance, durability, and mechanical ...

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Deemed the most advanced trimmer capacitors of their type to enter the RF/Microwave market, the SGNM series features durable, high-purity ceramic dielectrics, considered a new concept in the industry ...

The first British commercially available high-vacuum variable capacitors have been announced by the English Electric Valve Co. So 64 years ago, started a story in Electronics Weekly’s edition of March ...
