ATCDB12 is an accurate knob dial type capacitor decade box. Because of the main features listed above, it is a very useful tool for tuning analog electronic circuits where changing a capacitance is needed.

What's more, We have designed and have been making for 14 years the world’s only Super SMT Capacitor Kits™ which offer the most convenience for obtaining any value of SMT capacitors in the shortest time with the highest accuracy.

Our Super SMT Capacitor Kits™ are made based on the world’s only special container, Super SMT Component Enclosure™, which has 128 individually lidded coverlets and one final top cover. The foam pad inside the top cover keeps all the coverlets closed when the top cover is closed and locked. Each cover-let 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).

All the surface mount capacitors are pre-sorted and stored in Super SMT Component Enclosure™ with surface mount capacitor values printed clearly on each lid.
