The MCH series capacitors are the standard tantalum chip capacitors from UCC/NCC that are
designed for automotive use. These surface mount capacitors are designed for high reliability and
have excellent resistance against moisture and thermal shock. The MCH capacitors are available with
either a 20% or 10% tolerance.
Refer to the Mini-Glossary at the end of the tantalum chip capacitors section for additional technical
information and specifications.
