The PRAHT resistor network from Vishay Intertechnology

摘要

Having a resistor network available that can take the heat - all the way up to a very hot 215℃ - is a very good thing if you design jet engine control systems or oil down-hole extraction instrumentation or pressure sensors. For these designs and a lot more, the PRAHT four-resistor network from Vishay Intertechnology is really important. That's why we gave the Vishay network a 2012 Product of the Year Award. It's an important device that gives engineers a TCR of 10 ppm/℃, a tolerance of ±0.1% or ±0.5%, and a ratio tolerance down to 0.05% - over that wide temperature range. There are quite a few designs that just can't live without this new network.
