Modern servers require fast CPU power, long-time reliability, strong I/O external data throughput, and better scalability, all of which are supported by inductors.
The high current inductor is an important part of the server, if the design can be properly optimized, it can effectively improve the efficiency of the server.  In addition to higher current, higher operating temperature and higher frequency requirements for higher efficiency, other important selection criteria for inductors include: 5
1. Smaller size - reduce the circuit layout area
2. More stringent tolerance- ensure consistent circuit performance
3. Very low DC resistance (DCR) - improve power efficiency
4. Multiphase integration - reduce PCB footprint and number of components
