ATRDB12 is an accurate knob dial type resistor decade box. Because of the main features listed above, it is a very useful tool for tuning analog electronic circuits where changing a resistance is necessary.
What's more, we offer Resistor Kits™ which provides the most convenience for locating any value of SMT resistors in the shortest time with the highest accuracy. This helps you work smarter and faster saving time and money.

Our Super SMT Resistor Kits™ are the world’s only special container for storing resistors.  The Super SMT Component Enclosure™ has 128 individually lidded coverlets and one final top cover. The foam pad inside the top cover keeps all the coverlets sealed when the top cover is closed and locked. Each coverlet measures: 0.87" (L) x 0.59" (W) x 0.63"(D) or 22mm (L) x 15mm (W) x 16mm (D). The Super SMT Component Enclosure™ measures: 11" (L) x 8.5" (W) x 1.75"(H) or 280mm (L) x 216mm (W) x 45mm (H).
