It carries a continuous rated current of 90 A, with a maximum current of 100 A and a peak current of 200 A. The DC-rated value is 122.5 A. Inductance is 0.37 mH, with a relative inductive voltage drop of 4% at the rated measurement level. This is the component that sits between the converter and the line or load to limit di/dt and reduce commutation notches — critical for protecting the converter's power semiconductors and meeting EMC limits.
Lifecycle stage is listed as mature, meaning the design is stable and the part remains in the active catalog without near-term phase-out signals. No successor order code has been assigned. For a BOM-critical line, this is a low-risk procurement — no last-time-buy clock, no PCN on the horizon.
The enclosure is IP00 — no finger protection, no drip shield. Dimensions are 0.16 m depth, 0.225 m width, and 0.21 m height. Main circuit connection uses flat-type terminals, which match standard busbar or cable-lug interfaces in power converter cabinets. Thermal class H per IEC 60085 means the insulation system can withstand continuous hot-spot temperatures up to 180 °C — a generous margin for forced-ventilated or derated installations. Power loss splits into 131 W in the coil and 68 W in the iron core, totalling 199 W at rated conditions; that heat must be evacuated by the enclosure's thermal design.
The choke is designed and tested to EN 61558-2-20, the standard for small transformers and chokes for converter applications. Ambient temperature rating is 40 °C. For an MRO planner: this is a direct-fit spare for any Siemens converter line that calls out the 4EU2 family at 90 A. No rewiring or adapter plate is needed if replacing an identical unit — the flat terminals and mounting footprint are consistent within the series.
