Key Attributes
Product Description
General Series Multi-layer Ceramic Capacitors (MLCC)
Product Overview
This series of General Type MLCCs features a monolithic structure of laminated layers, offering high reliability and excellent soldering and solder resistance capabilities suitable for reflow and wave soldering. They provide high and stable capacitance. Class I capacitors (C0G, C0H) offer the most stable electrical performance, ideal for low-loss, high-stability high-frequency circuits. Class II capacitors (X7R, X5R, X7S, X7T, X6S, X6T) utilize materials with higher dielectric constants for increased capacitance and stable temperature characteristics, suitable for DC-blocking, coupling, bypassing, and frequency discriminating circuits.
