3 Pin Transistor Outline Hermetic Resistor Network
The three pin TO-18 package is suitable for single resistor
hermetic packaging with case and lid grounded for electrical
isolation. This unique package may also be used to provide a
voltage divider, but the user is cautioned that the center tap must
go to ground.
Review data sheet “7 Technical Reasons to Specify Bulk
Metal
®
Foil Resistor Networks.”
3 pins on a 0.100" pin circle– pin 3 case grounded.

NOTES:
1. These networks utilize Vishay Bulk Metal
®
Foil resistor
chips V5X5 and V15X5 or VTF15X10 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.
