ERU 19 Chokes

TDK ERU 19 Chokes feature a high-temperature ferrite core within a low profile, small footprint package. ERU 19 chokes have an inductance range of 1µH to 30µH and a saturation current range of 10.1A to 43A for B82559xA019 devices, and 11.5A to 48.1A for B82559xB019 modules. These energy storage chokes are magnetically shielded and feature helical winding. The series is AECQ200 qualified. Applications for TDK ERU 19 Chokes include DC-DC converters, voltage regulator modules (VRM), point-of-load (PoL) converters, and solar converters.
