Its 0.05 H inductance and 46.8 W coil power loss are sized for DC-link filtering in drives or power supplies — the 2.5 W energy content tells you it handles moderate ripple, not bulk storage. Open-frame IP00 design — no enclosure, so it mounts inside a cabinet on a sub-panel or chassis. Dimensions are 0.151 m wide × 0.151 m high × 0.129 m deep. Thermal class B (130 °C) per IEC 60085, ambient rated at 40 °C.","metaTitle":"Siemens 4EM5308-3CB00 Smoothing Choke, 10A DC, 690V","metaDescription":"Siemens SIDAC 4EM5308-3CB00 smoothing choke, 10A DC, 690V, 0.05H, IP00.
