IET is the World''s Leading Capacitance Standard Manufacturer. With 50+ years of stability data and history, IET Labs manufactures a full line of standard capacitors that will cover most any budget and application. From the world''s most stable to our cost-effective models We manufacturer units with a range of 1 pF to 10,000 µF
Selection and calibration of capacitors for use as Standards is a challenging task, especially since the accuracies required, depening on the application, can be very demanding for the test gear as well as for the secondary- and working-standards used.
2. Capacitance Calibration The precision measurement of capacitors for the purpose of calibration is generally based on a national primary standard of high accuracy, secondary/working Standards derived from it, and a capacitance- (or LCR-) meter used for the measurement (i.e. calibration) of the devices under test (DUT).
Our most popular capacitance standard is the one with a cost and flexibility that make it preferred. Typical capacitors, observed over decades, have shown random fluctuations of less than + 0.01% in measured capacitance with no evidence of systemic drift. They are available with a variety of connectors such as BNC and binding posts.
The SCA Standard Capacitor series have a capacitance range of 1 pF - 10,000 µF. They are highly stable, cost-effective capacitance standards with low temperature coefficient and low losses, making them our most popular capacitance standard.
IET Labs can also provide accredited calibration for Dissipation Factor-Measure using the AH2700A. IET Labs is one of just a few accredited calibration laboratories, for Capacitance-Measure using the Andeen-Hagerling AH2700A. This allows us to calibrate your capacitance standards at various frequencies from 50 Hz to 20 kHz.
Consequently, the GR1403 capacitors used for the calibration/verification of our IET1689 digibridge have this uncertainty (plus the related temperature drift uncertainty for a +/-2K temperature uncertainty; normal distribution). Thus, these capacitors are calibrated to 133ppm or 0,0133% worst case.
