New Vishay Flat Chip Resistor Arrays Provide Tracking TCR as Low as 10 ppm/K and Matched Tolerance of 0.1% in 0612 Package
MALVERN, PENNSYLVANIA - February 18, 2005 - Vishay Intertechnology, Inc. (VSH: NYSE) today announced that it has introduced two new series of flat chip resistor arrays that integrate four thin film resistors into a single 0612 surface-mount package. The Vishay Beyschlag ACAC 0612 precision series and ACAC 0612 professional series resistor arrays are ideal for applications that demand high component densities and accurate and stable resistor performance.
The ACAC 0612 precision series resistor arrays feature absolute TCR of 25 ppm/K and tracking TCR of 15 ppm/K, with tracking TCR of 10 ppm/K available upon request. The ACAC 0612 professional series resistor arrays feature absolute TCR of 50 ppm/K, with 25 ppm/K available upon request. The ACAC 0612 precision series arrays have absolute tolerance of 0.25% and matched tolerance of 0.1%, while the ACAC 0612 professional series arrays have absolute tolerance of 1%.
The resistor arrays have a footprint of 1.6 mm x 3.2 mm, a reduction of approximately 40% when compared to the use of four discrete 0603 resistors. Resistance options range from 100 Ù to 221 Ù, and arrays are available with four equal values, four different values, or two equal value pairs. Maximum power dissipation for the new arrays is 0.3 W, with individual resistors rated at a maximum of 0.1 W.
For arrays featuring differing individual resistance values the Rmin/Rmax ratio is 1:10 for the professional series arrays and 1:5 for the precision series arrays. Close tolerance matching of 0.1 % in the case of the precision series arrays ensures highly reliable and stable fixed resistor ratios.
The ACAC 0612 resistor arrays are suitable for use in voltage dividers, feedback circuits, and signal conditioning functions. Target applications include automotive engine control units, climate control, transmission controls and driver safety systems, mobile telecom base stations, medical instruments, precision measuring equipment, and high-end audio amplifiers. The arrays can also be used in sensing and management systems for PSUs and battery chargers.
The ACAC 0612 resistor arrays are lead (Pb)-free, and the pure tin plating provides compatibility with lead (Pb)-free and lead (Pb)-containing soldering processes. Extensive testing has proven the immunity of the plating against tin whisker growth, and the resistor arrays comply with the CEFIC-EECA-EICTA list of legal restrictions on hazardous substances (RoHS).
Pricing for ACAC 0612 resistor arrays ranges from approximately $0.06 to $1.00 in quantities of 100 pieces, depending on product specifications.
