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
