Vishay Foil Resistors
Bulk Metal® Foil Technology
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.
