Greetings

I'm unfamiliar wit the unit Ω || pF in a datasheet for a JFET operationa amplifier i'm looking at. The parameter is the input impedance.

10*10^13 || 8 Ω || pF

I'd assume that it means a 10 teraohm input impedance and then a 8 pF capacitance on the gate input.

Please correct me if i'm wrong. Or confirm if i'm right :)

Best regards.
 

Yes, the || denotes 'in parallel' so 1M || 1pF means 1M ohm in parallel with 1pF.
