These voltage dividers are the first choice for accurate and stable division. Two resistors simultaneously etched into a piece of foil
produce the maximum in TCR tracking without the need for curve matching of separate resistors. The size and very small footprint
of the divider 300144 is also very important. This is the smallest foil divider available. A variety of ratios and impedance’s are already
tooled and are shown in Table 1 on the following page. Small deviations from the ratios shown can be accommodated in the trim
allowance already included in each side of the divider. Larger departures from the ratios shown may require new artwork.
The 300145 is a pair of 300144 elements back to back in a single molded package. Although performance between dividers is not
quite as good as within each divider, it is the most accurate and stable full bridge or differential gain setting device made.
