Key Benefits
• Small size: 0.030 x 0.045 in. (PWA); 0.070 x 0.070 in. (PWB)
• Excellent power capability: 0.5 watts (PWA); 1.0 watts (PWB)
• Good power handling: 100 % rated power to + 70 ºC derated to 0 % power at + 125 ºC
APPLICATIONS
• High-power amplifier circuits where increased power loads require
specialized resistors
• Power supplies

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
Product may not be to scale
• Resistor material: Tantalum nitride, self-passivating
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.
APPLICATIONS
The PWA resistor chips are used mainly in higher power
circuits of amplifiers where increased power loads require a
more specialized resistor.
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.
