C6 Ceramic Disc Capacitor 100nF 104Z

Ceramic Disc Capacitor 100nF C6 104Z as used in the HJW
            Electronics Choccy Block TRF AM Radio KitC6 100nF 104Z Capacitor Schematic Symbol

The marking on these capacitors is 104Z.  104 is the capacitance value in picofarads (pF) where this is read as 1,0, followed by four zeros.  The Z is an indication of the temperature stability and dielectric properties.  In the circuit, C6 is used in conjunction with Q3 as part of an active rectifier demodulator to turn the radio signal into audio.

0.1uF =
100nF = 100,000pF
