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® Foil Resistor Networks.”) 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® 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.
