18 Pin Dual-In-Line Hermetic Resistor Network
The 18 pin “L” brazed DIP is still a 0.300" pin spacing package
but overlaps the mounting holes, providing added chip capacity.
It is a good choice for a 14 bit R/2R ladder of R = 5K. Select
Model 1460 for added chip area or additional pins. This
network can contain up to 80 V5X5 resistor chips.

Metal® Foil Resistor Networks.”)

1. These networks utilize Vishay Bulk Metal
®
Foil resistor
chips V5X5 and V15X5 or VTF15X5 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.
3. The V5X5 and V15X5 chip(s) can be intermixed in a
package.
