Vishay Electro-Films
Thin Film Power Resistors
Product may not
be to scale
The PWB series resistor chips offer a 1 W power rating in a
relatively small size. They offer one of the best combinations
of size and power available.
The PWBs are manufactured using 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 circuits of amplifiers where increased power loads require a more
specialized resistor.
