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.
