The MC series are the standard general purpose tantalum chip capacitors from UCC/NCC. These
capacitors are available in both a 20% or 10% tolerance. Typical applications for the MC series
include personal computers, cellular phones, VCRs and audio components. If smaller case sizes for a
given capacitance and voltage are required, please refer to the MCS or MCM series.
Refer to the Mini-Glossary at the end of the tantalum chip capacitors section for additional technical
information and specifications.
