DRWW
INF
The DRWW Coil Cores Fixed Axial Power Inductor is designed for power electronic circuits requiring stable inductance performance, reliable current handling capability, and effective noise filtering characteristics. Its axial leaded wire-wound structure provides strong mechanical stability and excellent suitability for through-hole PCB assembly.
Optimized for filtering and energy storage applications, this inductor ensures smooth current flow, reduced ripple noise, and stable operation in switching power supply environments.
The DRWW series is widely used in industrial and electronic systems where durability, electrical reliability, and consistent performance are required under continuous operating conditions.
Customized inductance values, current ratings, wire types, and core materials are available based on application requirements.
