FEATURES
Product may not be to scale
· 500mW power · Chip size: 0.030 x 0.045 inches
The PWA series resistor chips offer a 500mW power rating in t h e small size available. These offer one of the best combinations of size and power available. The PWA s are manufactured using Vishay Electro-Films (EFI) s o p h i s t i c a t e d thin film equipment and manufacturing technology. The PWAs are 100% electrically tested and visually inspected to MIL-STD-883.
· Resistance range 0.3 to 1M · Oxidized silicon substrate for good power dissipation · Resistor material: Tantalum nitride, self-passivating
APPLICATIONS
The PWA resistor chips are used mainly in higher power circuits of amplifiers where increased power loads require a more specialized resistor.
