Bulk Metal

30 Pin Flatpack Hermetic Resistor Network

The 30 pin 1" x 1" flatpack is the largest ceramic package offered

by Vishay. It will accommodate the greatest number of resistor

chips and offers the maximum pin availability in the lowest

profile. This package can contain up to 225 V5X5 resistor

chips.

ORDERING INFORMATION - 1476 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.

NOTE:

1. These networks utilize Vishay Bulk Metal

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

VTF15X5 Thin Film chips.

3. The V5X5 and V15X5 chip(s) can be intermixed in a package.
