**FH Guangdong Fenghua Advanced Tech** · Ferrite Beads · 1206

CBM321609U070T from FH Guangdong Fenghua Advanced Tech, in a 1206. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | First terminal electrode (Ni/Sn plated) of the bead, which is non-polarized; CBM321609U070T is 7 Ω at 100 MHz, 0.01 Ω max DCR, 6000 mA max rated current. |
| 2 | 2 | passive | Second terminal electrode (Ni/Sn plated) of the bead, which is non-polarized and interchangeable with the first; the rated current of 6000 mA max gives a surface temperature rise of no more than 40 °C. |
