The CS Series Capacitance Decade Box is a cost effective and commonly used capacitance decade box for production and educational applications.

The easy of use and 1% accuracy makes the CS Box ideal for daily verification of test equipment before measurements, troubleshooting in the field or on the factory floor.

The wide range of capacitance values from 50 pF to 1000 uF (depending on model) is indispensable in laboratory, R&D and teaching applications.

One nice feature of the CS Series is that it uses convenient side by side, color coded, switches allowing for direct reading of the capacitance value. There is no fumbling with multiple slide or rotary switches. Simply dial in the desired values and use.

Made of high impact plastic and weighing less than a pound, these capacitance decade boxes are very portable and can reduce clutter on a busy lab bench. The CS Series utilizes a variety of highly stable film resistors for values less than 10 uF and tantalum capacitors for higher values.
