Product Overview
The Caddock Type 1776 Precision Decade Resistor Voltage Dividers are designed for digital multimeters and range-switching instruments, offering exceptional performance through Caddock's Tetrinox resistance films. These compact, precision resistor networks provide higher performance and require less board space than discrete resistor sets or thin-film networks. 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. They are ideal for the precision input signal circuits of bench-type and laboratory digital instruments.
