Detail

datasheet

The SCA Standard Capacitor series are highly stable cost-effective capacitance standards with low temperature coefficient, low losses and a wide range of values of 1 pF - 10,000 µF. The cost and flexibility make this our most popular capacitance standard.

 From 1 pF to 10 pF, these are made from precision air capacitors. Up to 1 µF, the standard capacitors are constructed of fixed mica capacitors of very high stability for use as two- or three-terminal reference or working standards in the laboratory. Above 1 µF they are made with hermetically sealed polypropylene sulfide,

Typical capacitors, observed over decades, have shown random fluctuations of less than + 0.01% in measured capacitance with no evidence of systemic drift.
