They offer one of the best combinations of size and power available. The PWBs are manufactured us ing Vishay Electro-Films (EFI) sophisticated thin film equipment and manufacturing technology. The PWBs are 100 % electrically tested and visually inspected to MIL-STD-883.

FEATURES

  • Wire bondable
  • Power: 1 W
  • Chip size: 0.070 inches square
  • Resistance range: 0.3 Ω to 20 kΩ
  • Oxidized silicon substrate for good power dissipation
  • Resistor material: Tantalum nitride, self-passivating

APPLICATIONS

The PWB resistor chips are used mainly in higher power circui ts of amplifiers where increased power loads require a more specialized resistor.
