Giga Trim
Tiny trimmer capacitors. Straight-forward technique for fine RF and microwave circuits.
Increasing magnetic resonance applications caused Knowles Precision Devices's Voltronics Brand to launch an active engineering effort in this field years ago, one that continues today. Due to the severe non-magnetism requirements in these industries, we use only materials that exhibit no measurable magnetism. Commercial brass and plating materials are not acceptable. Our strict traceability and testing regimes insure this essential parameter. Most of our trimmers are internally sealed so that they withstand immersion in flux and solvents without leaking. Most of our non-magnetic trimmers have been used and tuned at temperatures as low as 4° K. Many of our selection of trimmers have been developed for specific customer needs – let us design a high performance trimmer for your application.
