Variable Substitution Resistor/Capacitor Boxes

In the ongoing development of analog electronic circuits, the routine fine-tuning of RC compensation networks is imperative. Despite the absence of user-friendly resistor and capacitor decade boxes in the market, we undertook the design and fabrication of our own solutions, which have proven highly effective and are now available for our customers.
Introducing the ATRDB12 and the ATCDB12 – both are precision knob-dial type variable resistor and capacitor decade boxes designed for circuits operating up to 1MHz. These devices provide accurate and flexible tuning capabilities.
For applications involving higher frequency circuits, specifically in the range of 1MHz to 10MHz, we engineered the ATRCT101. This compact RC decade mini tuner exhibits significantly lower stray capacitance and inductance, making it an ideal tool for use as a tunable resistor, capacitor, or a resistor-capacitor serial array. This versatile solution caters to the demanding requirements of circuits operating at elevated frequencies.
