Le = Effective Magnetic Path Length: 8.30 cm  Ae = Effective Cross Section Area: 1.15 cm2  Ve = Volume : 9.55 cm3 Al = Inductance Factor : 8365 nH  RoHS Compliant Application / Uses :  J material with permeability of 5000 is the most widely used ferrites core for common mode chokes. It is also used as EMI/RFI filters for amateur radio bands ( 3 Mhz to 30 Mhz) by wrapping the cables around the cores. Low Volume resistivity, and low core loss from 1 Khz to 1 Mhz range, it is also used as pulse transformers and low level wide band transformers. As Common mode chokes and filters, the effective range is filtering out noise from 500 Khz to 100 Mhz. But best attentuation is from 500 Khz to 20 Mhz.
