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, method 2032, class H or
class K.
APPLICATIONS
The PWB resistor chips are used mainly in higher power
circuits of amplifiers where increased power loads require a
more specialized resistor.
