Product Overview
GENERAL MLCCs are multilayer ceramic capacitors featuring a monolithic stacked structure for high reliability. They offer excellent soldering performance suitable for reflow and wave soldering, with high capacitance and stable performance. Available in Class I (COG, COH) for high-frequency, low-loss, and stable circuits, and Class II (X7R, X7S, X7T, X6S, X6T, X5R) for broader applications like DC blocking, coupling, bypassing, and frequency discrimination. These capacitors are widely used in various filtering, coupling, resonant, and high-frequency electronic circuits.
