1 / 3 page PWB www.vishay.com Vishay Electro-Films Revision: 04-Mar-13 1 Document Number: 61021 For technical questions, contact: efi@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Thin Film Power Resistors Product may not be to scale 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, method 2032, class H or class K. FEATURES • Wire bondable •Power: 1 W • Chip size: 0.070 inches square • Case: 0707 • Resistance range: 0.3 to 20 k • 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 PWB resistor chips are used mainly in higher power circuits of amplifiers where increased power loads require a more specialized resistor.
