PWB Thin Film Power Resistors

PWB Vishay Electro-Films Thin Film Power Resistors CHIP 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 .

Features

• Wire bondable
• Power: 1 W
• 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 APPLICATIONS The PWB resistor chips are used mainly in higher power circuits of amplifiers where increased power loads require a more specialized resistor.
