| 1442, 1445, 1446 Vishay Foil Resistors Bulk Metal(R) Foil Technology Dual-In-Line Hermetic Resistor Networks Vishay Model 1442, 1445 and 1446 networks incorporate all the performance features of Vishay Bulk Metal(R) Foil technology. The 8, 14 and 16 pin side brazed DIPs are a ceramic package. Ceramic has the advantage of electrical isolation on the underside, and, in DIP form, a favorable pin arrangement when two networks are to be placed side by side and connected together. Review data sheet "7 Technical Reasons to Specify Bulk Metal(R) Foil Resistor Networks." 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.

NO. 1 LEAD These networks utilize Vishay Bulk Metal(R) Foil resistor chips V5X5 and V15X5 or VTF15X5 Thin Film chips. 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. The V5X5 and V15X5 chip(s) can be intermixed in a package. NO.
