DESCRIPTION
The J210 Series is an N-Channel JFET single device
encapsulated in a TO-92 plastic package well suited for
automated assembly. The device features low leakage,
typically under 2 pA, low noise, under 10 nano volts per
square hertz at 10 hertz and high gain. This series is
excell ent for mixer, oscill ators and amplifier appli cations.
