1457 Vishay Foil Resistors Bulk Metal® 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® Foil Resistor Networks.”) Product may not be to scale THROUGH HOLE 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.
