High-performance nanocrystalline inductors reduce I/O and DC line noise

TTI IP&E – Europe now offers the FW series of nanocrystalline inductors from Chemi-Con. The material's high magnetic permeability decreases the core volume and the number of copper wire turns required to achieve a high performance, small size, and lightweight design. The common mode choke coils can be employed as input/output and DC line noise filters in various power source applications.

Since the curie temperature (magnetic transition temperature) is at 570C, the coil's characteristics are maintained even in high-temperature environments such as automotive applications. Also, advantages such as low resistance (1.2mOhm to 26mOhm max) and low heat generation enable the coil to be employed in power sources for medical equipment, communication base stations, and industrial equipment.

Compared to the conventional FL-V series coils, the magnetic permeability of the FW series at 10kHz has improved by approximately 150% (3.2mH to 37.1mH) while maintaining a high performance (1mH to 11.5mH) at 100kHz. Also, the impedance at 150kHz to 1MHz has improved.

Dermot Byrne, director of Industry Marketing Transportation, TTI Europe, recommends that engineers replace conventional ferrite coils with the FW series to downsize their designs: "For example, you could exchange two conventional ferrite coils with one FW series nanocrystalline coil of the same size."

The FW series nanocrystalline coils and cores can supply continuous operation 24/7. Other features include -40C to +130C applicable temperature range, AEC-Q200[1] compliance, and UL 94V-0 Type B (+130C) flammability and insulation rating.
