ValueTronics International, Inc. Standard 1407G

The 1407G is a used Capacitance Standard from General Radio. Engineers use direct current (DC) voltage standards to calibrate, standardize, normalize, and monitor drift, verify linearity, and establish regulation in electronic equipment. Standards are important during electronics compliance testing. Phase angle standards are ideal for calibrating many different electronics, including power analyzers, vector voltmeters, phase meters, phase sensitive instruments, and resolvers. Additional Features: 0.01 uF Standard Capacitor Stability: capacitance change is less than 0.01% per year. Accuracy: within plus or minus 0.05%, at 1kHz Temperature Coefficient of Capacitance: 20 plus or minus 10ppm/C The mica in the 1407G is selected for low dissipation factor. Interfacial polarization in the mica dielectric is a source of capacitance change with frequency at lower frequencies.
