Document 395 PFC Choke Core material Ferrite This power factor correction choke is designed specifically for the STMicroelectronics L6562 PFC controller. It is intended for use in IEC61000-3-2 compliant switch mode power supplies used in televisions, desktop PCs and high-end ac-dc adapters/chargers. Terminations RoHS compliant tin-silver over tin over copper-clad steel. Other terminations available at additional cost. Weight 75 g Ambient temperature –40°C to +85°C Storage temperature Component: –40°C to +85°C. Packaging: –40°C to +80°C The EB0057-DL is the RoHS-compliant version of the EB0057-C. It is electrically identical and fits the recommended PC board layout. Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity) Failures in Time (FIT) / Mean Time Between Failures (MTBF) 38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332 Coilcraft can design custom transformers with voltage, inductance and DCR values to meet your specific requirements.
