ORDERING INFORMATION - 1476 PARTS
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.
NOTE:
1. These networks utilize Vishay Bulk Metal
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.
