high voltage multilayer ceramic capacitors surface mount FH 0402B473K500NT meeting GB T 21041 2007 standards
Product Overview
High-Voltage Multi-layer Ceramic Capacitors (MLCCs) are designed for surface mounting and offer high voltage reliability for various DC high-voltage circuits. Built on advanced MLCC technology, these capacitors feature a monolithic laminated structure for high reliability, excellent soldering and resistance to soldering heat, making them suitable for reflow and wave soldering. They provide high and stable capacitance, adhering to GB/T 21041-2007 and GB/T 21042-2007 standards. Applications include analog/digital modems, LAN/WAN interfaces, lighting ballast circuits, voltage multipliers, DC-DC converters, and back-lighting inverter circuits.
