Diode Capacitance measured with HP 4279A or equivalent instruments (at OSC level 20 mVrms, ± 5 mVrms). Series Resistance measured with HP 4191A or equivalent instruments. The tolerance of two adjacent parts on a reel is within 3% at C2, C3, C6, and C8. The value of capacitance is the average of 2 back to back type diodes.
