12 Pin Transistor Outline Hermetic Resistor Network
The 12 pin TO-8 package is suitable for ladder networks up to ten bits and other more complicated networks. It is also a good choice when power dissipation is a consideration. This network can contain up to 49, V5X5 resistor chips. Review data sheet “7 Technical Reasons to Specify Bulk Metal® Foil Resistor Networks.” VISHAY CHIP MAXIMUM POWER RATING MODEL NUMBER CAPACITY (WATTS) @ +70 °C 1421 V5X5 - 49 chips 0.6 Watt 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.
