Vishay Foil Resistors
Bulk Metal
®
Foil Technology
Dual-In-Line Hermetic Resistor Networks
Vishay Model 1442, 1445 and 1446 networks incorporate all
the performance features of Vishay Bulk Metal
®
Foil
technology. The 8, 14 and 16 pin side brazed DIPs are a
ceramic package. Ceramic has the advantage of electrical
isolation on the underside, and, in DIP form, a favorable pin
arrangement when two networks are to be placed side by
side and connected together.
Review data sheet "7 Technical Reasons to Specify Bulk
Metal
®
Foil Resistor Networks."
Networks are built to your requirements. Send your
schematic and electrical requirements to the Applications
Engineering Department. (See data sheet "Network
Worksheet.") A unique part number will be assigned which
defines all aspects of your network.

Foil resistor chips V5X5 and V15X5 or VTF15X5 Thin Film chips.
2. The V5X5 and V15X5 chips have maximum resistance values of 10K and 33K respectively in Bulk Metal
®
Foil and 500K in VTF15X5 Thin
Film chips.
3. The V5X5 and V15X5 chip(s) can be intermixed in a package.
