HV Nonmagnetic Variable Trimmer Capacitor Works at Cryogenic Temperatures
Featuring high purity ceramic dielectrics, the SGNM series of high-voltage nonmagnetic variable capacitors from Sprague-Goodman Electronics can be sealed to 40 lbf/in2 (276 kPa), or used for cryogenic applications at temperatures as low as 4K. DC working voltage ranges from 1.5 kV up to 7.5 kV (DC withstanding voltage from 3 kV to 15 kV). Capacitance ranges start with 1 – 10 pF, and increase (in 5 pF increments) to 10-180 pF. The capacitors include also include nonrotating design and linear tuning with fine resolution.
