It's designed to sit in the DC link of a drive or power supply, filtering ripple current and reducing harmonic stress on capacitors and upstream rectifiers. Rated for 30 W power loss at 40 °C ambient with thermal class B insulation. The IP00 enclosure means it's an open-frame component — mount it inside a panel or cabinet. Termination is via screw-type or tab terminals on the main circuit. The windings are not selectable in parallel — it's a fixed-inductance unit. No official successor order code has been published by Siemens for this part. If you're freezing a BOM or planning a long-term supply, request a lifecycle status update at RFQ time. Dimensions: 0.129 m deep, 0.097 m wide, 0.111 m tall. No DIN-rail clip; it's a chassis-mount unit, so plan for a mounting plate or bracket. Because it's IP00, keep at least 20 mm clearance to grounded metalwork and adjacent components for airflow and creepage at 690 V. The screw/tab terminals need access for a screwdriver or spade connector — don't bury it behind a fixed panel.","metaTitle":"Siemens SIDAC 4EM5105-4CB00 Smoothing Choke, 10A DC, 20 mH","metaDescription":"Siemens SIDAC 4EM5105-4CB00 DC smoothing choke, 10A max, 20 mH, 690V, IP00, screw/tab terminals.
