# HCB3216KV-310T30

**TAI TECH** · Ferrite Beads · 1206

HCB3216KV-310T30 from TAI 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 of the two-terminal ferrite bead, a Pb-free Ag/Ni/Sn termination, rated 3000 mA max DC with 0.04 Ω max DC resistance and 31 Ω ±25% impedance at 100 MHz. |
| 2 | 2 | passive | Second terminal of the two-terminal ferrite bead; the bead is not polarized, so it is interchangeable with the first terminal and carries the same 3000 mA max rated current. |
