PWA Vishay Electro-Films Thin Film Power Resistors CHIP RESISTORS FEATURES • Wire bondable Product may not be to scale • 500 mW power • Chip size: 0.030 x 0.045 inches • Resistance range 0.3 Ω to 1 MΩ • Oxidized silicon substrate for good power dissipation • Resistor material: Tantalum nitride, self-passivating The PWA series resistor chips offer a 500 mW power rating in a small size. These offer one of the best combinations of size and power available. The PWAs are manufactured using Vishay Electro-Films (EFI) sophisticated thin film equipment and manufacturing technology. The PWAs are 100 % electrically tested and visually inspected to MIL-STD-883. APPLICATIONS The PWA resistor chips are used mainly in higher power circuits of amplifiers where increased power loads require a more specialized resistor.
