Specifications for inductor L5 for CW305

Hello,

we are using CW305 and we need to know the value of the inductor L5 (on schematic). We saw that it is marked with an 800R/8A but we werent able to find any correspondance with that.

thanks in advance!

Hi,

I’m not 100% on this, but I think 800R refers to impedance and that the inductance value isn’t particularly important to the circuit. @coflynn can answer better than I can, though.

Hello,

Indeed as Alex says this is a ferrite bead, so it specifies an impedance at some test frequency.

Here is a link to the part number on the manufactures site which includes the datasheet along with any other information they offer: HR2220V801R-10

Thanks,

-Colin

Thank you both @coflynn and @Alex_Dewar for your answers. Seems like it is as you say.
