Product Description
Product Description The Extech 380405 Capacitance Decade Box is very popular for product design testing and calibration because it can be substituted into a circuit and function in the place of any component with a standard value easily. Alternatively, it can be used to identify the best value for circuit operation then read that value from the switches. A capacitor of the size indicated by the decade box switches can then be put into the circuit. From the Manufacturer Capacitance substitution box is excellent for circuit development. It features 5 decades substitution from 100pF to 11,111?F. 5% accuracy. 3 binding posts permit isolated substitutions and grounding the case separately.

Customer Reviews
Solid resistor decade box, feels really nice on my hands, no a metal box but does not feel flimsy. Switches feel very solid, and all the switches external metal case are connected to ground. The yellow box looks nice on the bench. Does not take too much space.Some of these resistor decade boxes cost 100’s or 1000’s of Dollars, that’s crazy. Unless you are designing the next iPhone replacement, this is all you need. Resistor are 1%.The front panel cuts out are no precise. Look the 1MΩ switch, as a result the switch feels kind of rough when set to “IN” or “OUT.” This is the worse switch on the box I got. Some other switches are like that, but they don’t feel too bad.Overall, good box. I like it. I think 5 stars are well deserved. Price is good. Made in Taiwan. Where else, right?
