Vishay Foil Resistors
Bulk Metal® Foil Technology
4 Pin Transistor Outline Hermetic Resistor Network
The four pin TO-18 package is the smallest available in the
miniature hermetically sealed series of networks. It should be
the first choice for simple networks requiring multiple R's. This
network can contain up to 5, V5X5 resistor chips. Note that
case grounding limits the circuit options to a two resistor divider.

Metal Foil Resistor Networks.”

ORDERING INFORMATION - 1403 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.
