Product Overview
Caddock Electronics introduces the Type 1776 Precision Decade Resistor Voltage Dividers, now available in new, smaller models at a lower cost. These compact precision resistor networks leverage Caddock's Tetrinox resistance films to deliver exceptional performance for the input signal circuits of bench-type and laboratory digital instruments. They offer higher performance than discrete resistor sets and thin-film networks, requiring less board space. The expanded family includes 3, 4, and 5-decade voltage dividers with ratios from 10:1 to 10,000:1, featuring 1,200 volts continuous ratings and overvoltage capabilities up to 2,000 volts. Various combinations of ratio and absolute tolerance, and ratio and absolute temperature coefficient are available.
