It's designed to filter ripple current on DC bus links in drives, power supplies, or converter circuits where a smooth DC voltage is critical for downstream electronics or motor control. The 3.5A maximum DC current (3.2A rated) sets the continuous load limit — this choke saturates above that, so it's sized for a 3A or smaller DC bus. The 0.16H inductance at 300Hz operating frequency gives the ripple attenuation; at lower switching frequencies the impedance drops, so verify your converter's PWM rate against the 300Hz rating. The 690V DC insulation voltage covers 400VAC rectified links with margin, but not 690VAC direct — that's the DC-side rating, not line-to-line AC. IP00 means no enclosure — this is a panel-mount component that must live inside a cabinet with IP54 or better. The screw-type and tab terminals accept ring lugs or fork terminals; the tab option suits quick-connect wiring in high-vibration environments. Thermal class B per IEC 60085 means the winding insulation withstands 130°C hot-spot — adequate for most industrial enclosures with forced or natural convection at 40°C ambient. ## Deployment context This choke mounts on a panel or chassis via its own base — no DIN-rail clip. The 0.129m depth, 0.097m width, and 0.111m height mean it fits a standard 200mm-deep cabinet with clearance for ventilation. The 28W coil power loss plus 0.6W iron-core loss totals about 29W heat to dissipate; allow 50mm air gap around the body or a small fan in a sealed enclosure.","metaTitle":"Siemens SIDAC 4EM5104-5CB00 Smoothing Choke, 3.5A DC, 0.16H","metaDescription":"Siemens SIDAC 4EM5104-5CB00 smoothing choke, 1-phase, 690V DC, 3.5A max, 0.16H inductance, IP00, screw/tab terminals.
