AND TEC I INNOVAT O L OGY PWA and PWB N HN THIN FILM RESISTORS O 19 62-2012 PWA Vishay Electro-Films Thin Film Wire Bondable Power Resistors Thin Film Power Resistors PWA 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.
