The Siemens SIDAC 4EM5000-4CB00 is a single-phase smoothing choke rated for 3 A DC (3.3 A maximum) with an inductance of 0.1 H and a rated operating voltage of 600 V DC. It's built to EN 61558-2-20, the standard for chokes used in power supplies and DC-link circuits. The 33 W coil power loss and thermal class B insulation (130 °C continuous) mean this choke is designed for steady-state DC filtering, not pulsed or high-frequency switching. The 0 Hz operating frequency confirms it's a line-frequency smoothing choke for rectified DC buses.
The IP00 enclosure means no dust or splash protection — this choke is intended for inside a panel or enclosure, not for open-air mounting. Screw-type and tab terminals on the main circuit make for straightforward wiring with ring or fork lugs. Depth is 0.115 m, width 0.097 m, height 0.111 m. This choke fits a standard control cabinet.
