As a high-power radial lead wirewound inductor, the DR 1018 Filter Choke uses high-saturation magnetic core material and precision layered winding, effectively preventing performance degradation from core saturation and ensuring stable filtering under high-current operation. Its radial through-hole package fits traditional PCB insertion processes, and the compact size enables flexible integration into dense circuit layouts, balancing mounting convenience and space utilization.

With a 250VAC rated voltage, 2000VAC dielectric withstand voltage and ≥100MΩ insulation resistance, it provides reliable electrical isolation. Operating at -20℃ to 105℃ with a maximum temperature rise ≤45℃ and 9.0A maximum current capacity, it supports long-term work in complex environments and meets the needs of medium-low voltage switches and high-power switching power supplies. Widely applied in power filter circuits, EMI suppression and signal purification, it efficiently eliminates clutter and blocks electromagnetic interference for stable equipment operation.

As a high-performance passive magnetic filter, the DR 1018 features high current-carrying capacity, compact size and stable filtering, with customizable specifications for diverse circuit requirements. It is a core component for medium-low voltage high-power electronics and high-density filter modules, ideal for industrial and civil electronic applications.
