Its 0.3mH inductance smooths the DC bus ripple on drives, inverters, or power supplies — the kind of job that keeps downstream capacitors and semiconductors from taking a beating. The 300Hz operating frequency tells you it's built for the switching side of a DC link, not line-frequency filtering. Total power loss runs 28.9W (28.1W in the coil plus 0.8W in the iron core), and it's wound to thermal class B per IEC 60085, meaning a 130°C hot-spot limit. That's standard for this size of DC choke — no derating surprises if the panel ambient stays under 55°C. IP00 with free cable ends for the main circuit connection — so it's a panel-mount component, not something you bolt outside or near washdown. The footprint is 0.121m wide by 0.149m deep by 0.109m tall, which is compact for a 98A DC choke. Plan for the free conductor ends to land on a terminal block or busbar inside the enclosure; no plug-in convenience here. Marked as mature lifecycle — meaning it's not in active promotion but still available through distribution channels. If you're freezing a BOM or filling a repair, send the order code and we'll quote it.","metaTitle":"Siemens SIDAC 4EM5214-8CB00 Smoothing Choke, 98A DC, 0.3mH","metaDescription":"Siemens SIDAC 4EM5214-8CB00 smoothing choke, 1-phase, 360V DC, 98A max, 0.3mH.
