ESAW Capacitance Substitution Box EEC-211

Comprising 12 non-polarised capacitors ranging from 100pF to 0.47?F (470?F) using standardly preferred values, in step ratios of approximately 1:2 Selection is by means of a rotary switch and the external connection is via a pair of 4mm sockets. All capacitors are of ± 2% tolerance, 250VD.C.

Working with values as follows:

100pF, .001?F, .0022?F, .0047?F, .01?F, .022?F, .033?F, .047?F, .1?F, .22?F, .33?F, .47?F.
