  • Chip size: 0.030" x 0.045"
  • Case: 0503
  • Resistance range 0.3  to 1 M
  • Oxidized silicon substrate for good power dissipation
  • Resistor material: Tantalum nitride, self-passivating
  • Material categorization: fo r definitions of compliance please see www.vishay.com/doc?99912

APPLICATIONS

The PWA resistor chips are used mainly in higher power circuits of amplifiers where increased power loads require a more specialized resistor.
