Vishay Intertechnology Enhances Precision Thin Film Chip Resistor Arrays With Tighter Tolerances and Temperature Coefficients

Vishay Intertechnology Enhances Precision Thin Film Chip Resistor Arrays With 
Tighter Tolerances and Temperature Coefficients for
Automotive and Industrial Applications 
MALVERN, PA -- (Marketwired) -- 05/16/13 --   Vishay Intertechnology,
Inc. (NYSE: VSH) today announced that the company has enhanced its
ACAS 0606 AT and ACAS 0612 AT precision thin film chip resistor
arrays with tighter absolute tolerance, relative tolerance, and
relative TCR for the new S, T, and U accuracy grades. Offering two
and four integrated resistors on one substrate, respectively, the
ACAS 0606 AT and ACAS 0612 AT lower costs when compared to using
multiple high-precision discrete resistors, while at the same time
their stable divider ratio improves the stability of the application. 
For increased accuracy, the Vishay Beyschlag ACAS 0606 AT and ACAS
0612 AT combine their high-temperature operation to +155 degrees C
with tight absolute tolerance of 0.1 %, relative tolerance of 0.05 %,
absolute TCR down to 10 ppm/K, and relative TCR down to 5 ppm/K. The
devices offer resistance from 47 ohms to 150 kilohms, with equal or
different resistor values, and maximum resistance ratio of 1:20.  
In addition to excellent high-temperature performance, the ACAS 0606
AT and ACAS 0612 AT are extremely robust against harsh environmental
conditions and provide superior moisture resistivity of l delta R/Rl
less than 0.5 % at +85 degrees C and 85 % relative humidity for 1000
hours. The devices offer a 1000 V ESD capability, a 75 V operating
voltage, and maximum rated dissipation to 0.125 W per element. For
automotive applications, the resistors are qualified according to
AEC-Q200. 
The new resistor arrays are ideally suited for precision analog
circuits, voltage dividers, and feedback circuit applications that
require extraordinarily stable fixed resistor ratios. Typical
applications will include automotive electronics, including engine
control units, gear box controls, safety, power supply electronics,
body electronics, braking systems, climate control, steering
technology, and lighting; and industrial electronics, such as energy
management, measurement control, sensors, scales, and precision
amplifiers. 
Samples and production quantities of the enhanced resistors are
available now, with lead times of six to eight weeks.
