HP / Agilent 16380A Standard Air Capacitor Set (1pF to 1000pF)

The HP/Agilent 16380A Standard Air Capacitor Set is a four-component precision calibration standard for verifying LCR meters and impedance analyzers. It comprises discrete air-dielectric capacitors spanning 1 pF to 1000 pF - covering 1 pF, 10 pF, 100 pF, and 1000 pF nominal values. Each capacitor achieves ±0.1% nominal accuracy with ±0.01% calibration accuracy and exhibits exceptional long-term stability at less than 300 ppm/year.

The dissipation factor remains below 0.0001, making these standards ideal for metrology labs, calibration departments, and manufacturing test environments requiring traceable, repeatable measurements.
