It's built for DC-link ripple filtering in drives, power supplies, or any circuit where a clean DC bus is required. The 5 H inductance at 0.9 A gives a substantial smoothing effect at the 300 Hz operating frequency — think post-rectifier filtering on a 6-pulse or 12-pulse drive input section. Total power loss sums to 47.5 W (46.4 W in the coil plus 1.1 W in the iron core), so this choke will run warm. The thermal class B winding insulation (130 °C hot-spot, per IEC 60085) handles that heat in a 40 °C ambient. IP00 means no enclosure — it's a panel-mount component that needs to live inside a cabinet with proper ventilation or forced cooling. Dimensions are 0.151 m wide by 0.151 m high by 0.129 m deep — roughly a 150 mm cube. The screw-type and tab terminals accept standard ring or fork lugs for the main DC circuit. Mounting is via the core frame; no DIN-rail clip is mentioned, so expect a bolted panel mount. The 5 H inductance at 0.9 A means the choke is physically sized for the core cross-section needed to avoid saturation at rated current.","metaTitle":"Siemens SIDAC 4EM5311-5CB00 Smoothing Choke, 0.9 A DC, 5 H","metaDescription":"Siemens SIDAC 4EM5311-5CB00 smoothing choke, 1-phase DC, rated 0.9 A / 5 H / 690 V.
