Sprague-Goodman's SGNM line is one of the industry’s first high voltage, non-magnetic, ceramic dielectric trimmer capacitor lines. The ceramic dielectric makes the parts more stable and versatile than other high voltage capacitors while offering a more compact design. A variety lead configurations, including surface mount, and extended shaft options are available. The product line is high voltage and Q, along with reliability and stability that the industry needs for next generation MRI and NMR projects. The SGNM series may be tuned at temperatures as low as 4 K for use in cryogenic applications. Typical applications include MRI and NMR coils, transmitting, and receiving sections of MRI and NMR machines. The SGNM is internally sealed to withstand up to 40 PSI and a residual magnetic value less than 20 nT.
