The MCS series is a general purpose tantalum chip capacitor series from UCC/NCC with higher
CV values. This allows for smaller case sizes compared to the MC series. These capacitors are
available with a 20% tolerance. Ideal applications for the MCS series include personal computers,
cellular phones and miniature audio components. If smaller case sizes are required, please refer to
the MCM series.
Refer to the Mini-Glossary at the end of the tantalum chip capacitors section for additional technical
information and specifications.
