Size
The MCM series is the highest CV tantalum chip capacitor series from UCC/NCC. These CV ratings
allow for the smallest case sizes for a given value. The MCM series is available with a 20%
tolerance and has the highest capacitance values of all our tantalum chip capacitors. These general
purpose tantalum chips are ideal for use in computers and cellular phones, where very small case
sizes are required.
Refer to the Mini-Glossary at the end of the tantalum chip capacitors section for additional technical
information and specifications.
