Thin Film Power Resistors

FEATURES

•

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.

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

APPLICATIONS

The PWA resistor chips are used mainly in higher power

circuits of amplifiers where increased power loads require a

more specialized resistor.
