Its 0.0022 H inductance smooths the DC link ripple in rectified supplies. The 300 Hz operating frequency matches the ripple from a single-phase bridge rectifier. At 55 °C ambient and Class B insulation, it is rated for continuous duty inside an enclosed panel. Total power loss splits between the coil (20 W) and the iron core (2 W), for 22 W total at rated current. ## Mounting and termination — what the IP00 rating means for your panel IP00 means no ingress protection — this choke has no enclosure. The free cable endings (Type of electrical connection for main current circuit: free cable endings) require a terminal block or direct crimp connection inside the panel; there is no built-in lug or screw terminal. Dimensions are 0.115 m depth, 0.097 m width, 0.111 m height. The free cable ends require strain relief and a clean wiring path to the DC bus. ## Lifecycle and compliance — what a mature-stage part means for procurement That typically means the design is stable and the part has been in production for years, but it is not in an active growth or new-introduction phase. For a smoothing choke — a passive component with no firmware or moving parts — mature is a comfortable place: no surprise EOL notice next quarter, but also no guarantee of indefinite availability. The part is UL/CSA-recognized per EN61558-2-20, which covers safety of chokes and transformers. That recognition is what lets it go into UL-listed panels without a separate component evaluation.","metaTitle":"SIDAC 4EM5010-1CB00 Smoothing Choke, 25A DC, 750V, 2.2 mH","metaDescription":"SIDAC 4EM5010-1CB00 single-phase smoothing choke.
