Size
The MCR series are new low impedance tantalum chip capacitors available from UCC/NCC. These
capacitors have a standard 20% tolerance and are available in the D case size. The MCR series
capacitors are specifically designed for use as filters at high frequencies and are ideal for small power
supplies due to their low impedance.
Refer to the Mini-Glossary at the end of the tantalum chip capacitors section for additional technical
information and specifications.
