| 1457 Vishay Foil Resistors Bulk Metal(R) Foil Technology 18 Pin Dual-In-Line Hermetic Resistor Network The 18 pin "L" brazed DIP is still a 0.300" pin spacing package but overlaps the mounting holes, providing added chip capacity. It is a good choice for a 14 bit R/2R ladder of R = 5K. Select Model 1460 for added chip area or additional pins. This network can contain up to 80 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 - 1457 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. 0.100 TYPICAL (2.54) FIGURE 2 - SAMPLE CIRCUIT DESIGNS AND CHIP LAYOUTS NOTE: Usable area is represented by the dotted lines-- a rectangle 0.250 Inches x 0.800 Inches.
