It handles a rated operating voltage of 690 V and is designed for a 300 Hz operating frequency — typical for DC-link ripple filtering in variable-speed drives or power supplies where the DC bus sees six-pulse rectifier harmonics. The 16.2 A rated value is the continuous design point; the 18 A maximum gives headroom for short-term overloads. Insulation class B per IEC 60085 means a 130 °C temperature class on the winding, adequate for most industrial enclosures at a 40 °C ambient. Dimensions are 0.129 m deep, 0.097 m wide, and 0.111 m high. Mounting is via the core clamping bolts or a separate bracket — no DIN rail footprint, so plan for a dedicated mounting plate or chassis base. Total power loss is 28.6 W — 28 W from the coil and 0.6 W from the iron core. That heat must be conducted out of the panel; ensure the mounting surface or adjacent airflow keeps the core temperature within class B limits. The 1.22 W energy content figure is the stored magnetic energy at rated current, relevant for sizing discharge resistors or snubbers if the circuit is interrupted rapidly.","metaTitle":"SIDAC 4EM5107-8CB00 Smoothing Choke, 18A DC, 7.5mH, 690V","metaDescription":"SIDAC 4EM5107-8CB00 single-phase DC smoothing choke. 18A max, 7.5mH, 690V insulation, IP00, screw/tab terminals.
