Adjustable Resistor Decade Box

The ATRDB12 Adjustable Resistor Decade Box is a high-precision, eight-decade resistance selector designed to provide rapid and accurate resistance changes across a wide range. Ideal for lab testing, analog circuit tuning, network simulation, and prototyping, this unit enables engineers to quickly dial in the exact resistance value needed without the hassle of replacing discrete resistors.

Main Features

• Wide resistance range: 0.36 ?? to 10 MΩ across 8 decades
• High resolution: 0.1 ?? in the lowest decade for precise low-value settings
• High accuracy: ±1 % tolerance typical
• Durable long-life rotary switches, designed for frequent value changes
• Compact, rugged metal enclosure for durability and ease of handling
• 100 % lead (Pb)-free and fully RoHS compliant
• Quick value reading via clearly labeled dials, enabling rapid changes during prototyping or testing

Typical Applications

• Analog amplifier and filter network tuning
• Simulation of resistor networks in prototyping and debugging
• Educational labs for hands-on circuit experiments
• Portable bench or field-use when flexible resistance variation is required
