This document introduces the external dimensions, temperature characteristics, packaging style, capacitance range, and features of the MCH21 chip capacitors. The chip capacitors achieve high capacitance through thin and multi-layer technology and have non-polarity and lead-free plating terminals. Depending on the temperature characteristics and capacitance range, this model is suitable for thermal compensation capacitors, high dielectric constant capacitors, and miniature high capacitance capacitors.
