Bulk Metal

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

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

and 500K in VTF15X5 Thin Film chips.
