| Document 395 PFC Choke 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. The EB0057-DL is the RoHS-compliant version of the EB0057-C. It is electrically identical and fits the recommended PC board layout. Coilcraft can design custom transformers with voltage, inductance and DCR values to meet your specific requirements. Contact Coilcraft for more information or for free evaluation samples. Part number EB0057-DL Inductance1 10% (H) 150 Primary DCR max (Ohms) 0.09 Core material Ferrite Weight 75 g For STMicroelectronics L6562 PFC Controller Terminations RoHS compliant tin-silver over tin over copper-clad steel. Other terminations available at additional cost. Ambient temperature -40C to +85C Storage temperature Component: -40C to +85C. Packaging: -40C to +80C Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / 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 Packaging 50 parts per tray PCB washing Only pure water or alcohol recommended Isolation2 (Vrms) 4800 Turns ratio pri : aux 8:1 Isat3 (A) 10.0 Irms4 (A) 4.0 1.
