PWB

Vishay Electro-Films

Thin Film Power Resistors

FEATURES

• Wire bondable

Product may not

• Power: 1 W

be to scale

• 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

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.

APPLICATIONS

The PWB resistor chips are used mainly in higher power circuits of amplifiers where increased power loads require a more

specialized resistor.
