Power purification. It adopts a composite filtering architecture, and the core filter uses a large-capacity ceramic multilayer capacitor array (72 pieces in parallel, a single piece of 10uf, ultra-low esr, and almost zero internal resistance). The energy storage filter uses a supercapacitor combined with a solid-state capacitor. The auxiliary filter uses an automotive-grade integrated inductor, a metal film capacitor, a calibration capacitor, a silver-tantalum capacitor, etc., which has an excellent effect. It can significantly increase the dynamics of the linear power supply and significantly suppress the ripple of the switching power supply. The ripple suppression rate is measured to be more than 80% to 90%! This model is suitable for switching power supplies and linear power supplies, and is suitable for vehicle-mounted. It is suitable for use in decoding headphone amplifiers, digital broadcasts, small hosts, nas and other devices, with obvious improvements. Scope of application: voltage 5V-25V, maximum supported current 10A;The input voltage and output voltage are the same, and the voltage is not changed. Device interface: DC2.1, DC2.5, terminal, TypeC Filter capacity: 603370 uf The polarity is positive inside and negative outside How to use: plug and play. Follow the direction of the arrow and let the electricity enter from one side and exit from the other side. Multiple interfaces are used to be compatible with multiple inputs and outputs. One input and one output is recommended, and one input and four outputs are supported at most! But the premise is that your power supply can support so many devices.
