Potentiometers & Trimmer Resistors - Electronic Goldmine

Voltage Controlled Resistor FetDesigned for small signal electronic attenuators,filters, amplifier gain control,oscillator amplitude control, etc. Made bySiliconix part #VCR2N, these have been speciallydesigned to be a 3 terminal variable resistor wherethe resistance value between two of the terminalsis controlled by a voltage applied to the third. Theseare prime, fully marked T018 metal case resistorFETS with a drain-source ON resistance range of20Ω min. to 60Ω max. Complete with 10 pages containinginfo, specs, formulae and application notes.Very unique, interesting and useful device!G4257 2/$1.00G4257A 100/$40.00High Voltage Enhancement ModeN-Channel MOSFET Type VN0535This features a BV DSS =350V, R DS =35andC ISS =45pf.
