Product Description
Product Overview
This product is a Multi-layer Ceramic Capacitor (MLCC) designed for high-voltage applications. It is suitable for coupling, wave filtering, and resonant functions in various power supply and lighting circuits, including switch power supplies, AC-DC and DC-DC power chargers, networking/communication interfaces, LCD backlight unit power supplies, and energy-saving lamps. The MLCCs are available in a range of standard sizes and offer different temperature characteristics (C0G, X7R, X5R) with precise capacitance tolerances and rated voltages.
Product Attributes
- Terminal Composition: Au/Ag-Ni-Sn (From the inside out)
- RoHS/REACH Compliance: Meets RoHS and REACH standards.
