Thin Film Power Resistors
Product may not be to scale
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, method 2032, class H or
class K.
FEATURES
Wire bondable
500 mW power
Chip size: 0.030" x 0.045"
Case: 0503
Resistance range 0.3 to 1 M
Oxidized silicon substrate for good power
dissipation
Resistor material: Tantalum nitride, self-passivating
Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
The PWA resistor chips are used mainly in higher power
circuits of amplifiers where increased power loads require a
more specialized resistor.
