Ferrite Rod Core is a cylindrical ferrite core, can be easily assembly with a spring coil or wind wire directly. It's widely used for radio antenna, LF/HF RFID antenna, choke coil, inductor, DC power filter, DC signal filter and transformer. Due to the open magnetic structure, the core can accept large DC bias before saturate. The rods
are design to use for MW and shortwave antenna coils; in high frequency applications they have low loss characteristics.
Initial Permeability (μi):                       400±20%
Relative loss factor tanδ/µi (×10–6 )   50 (100KHZ)
Saturation Flux Density (Bs):              250mT
Remanence (Br):                                120mT
Coercivity (Hc):                                   80A/m
Curie Temperature (Tc):                      120℃
Applied Frequence                              <3.5MHz
