choke transformer help

hey there,
i wonder if anyone can help me out here
first off, i'm having trouble finding information on a certain component, a choke transformer part number 25E06342S01, i can't find a data sheet on this part just its cost, its for an alpine amp, secondly i'm a little fuzzy on what a choke transformer actually does, if anyone can offer some info that would be great..

I Have No Info on that Part Number, But Know the Manufacturer would be a help.

As to its Purpose, Typically it is used in Conjunction with a Filter Capacitor to Reduce Ripple in a DC Supply. Or it can be used in Other Filter Application. Your letter doesn't give enough info to tell what purpose this choke is serving.

If you give the model of the Alpine amp, someone may have a schematic.
