Inductance is 5 mH. This choke smooths the DC bus ripple in drives, power supplies, or converter circuits — the 5 mH inductance filters the switching-frequency ripple to a level the downstream DC link can handle. Coil power loss is 28 W; iron-core loss adds 0.6 W, so total dissipation sits at 28.6 W. Thermal class B (130 °C rise) per IEC 60085 means the winding insulation handles a 130 K temperature rise above the 40 °C ambient. The IP00 enclosure is open-frame — it mounts inside a panel or cabinet, not in a washdown or outdoor location. The footprint is 0.097 m wide by 0.129 m deep by 0.111 m high — roughly 97 mm × 129 mm × 111 mm. That depth means it needs clearance behind the panel door or inside the cabinet; the 97 mm width fits a standard DIN-rail mount if the choke has a baseplate adapter (the evidence does not specify the mounting method, but the dimensions are consistent with a chassis-mount or baseplate-mount choke). Plan for the 28.6 W heat dissipation in the enclosure thermal budget.","metaTitle":"Siemens SIDAC 4EM5104-6CB00 Smoothing Choke, 20A DC, 5 mH","metaDescription":"Siemens SIDAC 4EM5104-6CB00 smoothing choke, 1-phase, 690V DC, 20A max, 5 mH, IP00, screw/tab terminals.
