It is designed for DC-link filtering in drives and power supplies, smoothing current ripple at operating frequencies up to 300 Hz. The 690 V insulation voltage (rated) and thermal class B (130 °C rise) per IEC 60085 suit it for industrial power conversion stages where a low-loss iron-core choke is needed. The choke measures 0.151 m wide by 0.151 m high by 0.129 m deep — a compact footprint for a 6.3 A DC-rated inductor. Connections are via screw-type or tab terminals, compatible with ring lugs or fork terminals common in power wiring. Rated current of 6.3 A DC (max 7 A) sets the continuous load the choke can carry without exceeding the 47 W coil loss and 1.1 W iron core loss at 40 °C ambient. The 0.1 H inductance at 300 Hz operating frequency provides effective ripple attenuation for a 6.3 A DC bus — the energy storage of 2.45 Ws (joules) per cycle defines the smoothing capacity. Thermal class B (130 °C) means the winding insulation withstands a 130 °C hot-spot temperature, which is standard for general-purpose industrial chokes.","metaTitle":"Siemens SIDAC 4EM5308-4CB00 Smoothing Choke, 6.3A DC, 0.1H","metaDescription":"Siemens SIDAC 4EM5308-4CB00 smoothing choke, 1-phase, 6.3A DC rated, 0.1H inductance, 690V insulation, IP00.
