Product details

The SIDAC 4EM5308-2CB00 is a single-phase DC smoothing choke rated 14 A DC, 0.025 H, 690 V, 300 Hz, thermal class B. IP00 rating means no enclosure. Screw/tab terminals accept ring lugs. Dimensions are 0.151 m by 0.151 m by 0.129 m.

The 14 A DC current, 0.025 H inductance, and 690 V insulation voltage define fit. Coil loss is 46.8 W; iron-core loss is 1.1 W. The 300 Hz operating frequency is the ripple frequency the choke is designed to filter — typical for a 6-pulse rectifier on a 50 Hz line (300 Hz ripple) or a 60 Hz line (360 Hz). If your drive's switching frequency is higher (4 kHz, 8 kHz), this choke still provides DC-link smoothing but the core losses will increase; the 1.1 W iron loss figure is at 300 Hz, not at higher frequencies. For a PWM drive front-end, confirm the core material's frequency response with the manufacturer.

Mounting: 0.151 m cube footprint. Screw/tab terminals face one side. IP00 body is bare assembly. Thermal: the 46.8 W coil loss plus 1.1 W core loss totals roughly 48 W of heat to reject. In a ventilated cabinet with natural convection, that's manageable; in a sealed NEMA 4X enclosure, forced airflow or a larger cabinet volume is needed to keep the ambient below 40 °C.

Frequently asked questions

What compliance documentation does SIDAC provide for 4EM5308-2CB00?

The evidence does not list RoHS, REACH, UL, or IEC certifications for this part. The design reference is EN 61558-2-20, which covers chokes. For specific compliance documentation, request it with the RFQ.
