| 1422 Vishay Foil Resistors Bulk Metal(R) Foil Technology 16 Pin Transistor Outline Hermetic Resistor Network The 16 Pin TO-8 package is suitable for ladder networks up to 12 bits and other more complicated networks. It is also a good choice when power dissipation is a consideration. This network can contain up to 49 V5X5 resistor chips. Review data sheet "7 Technical Reasons to Specify Bulk Metal(R) Foil Resistor Networks." Product may not be to scale ORDERING INFORMATION - 1422 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.

These networks utilize Vishay Bulk Metal(R) 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(R) Foil and 500K in VTF15X5 Thin Film chips. 3. The V5X5 and V15X5 chip(s) can be intermixed in a package. 45 0.029 -0.033 (0.74 -0.84) 0.029 -0.033 (0.74 -0.84) FIGURE 2 - SAMPLE CIRCUIT DESIGNS AND CHIP LAYOUTS NOTE: Usable area is represented by dotted lines-- a square 0.350 Inches x 0.350 Inches.
