# YI201209U601-2R5T

**YJYCOIN** · Ferrite Beads · 0805

YI201209U601-2R5T from YJYCOIN, in a 0805. 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 | Terminal 1 of the two-terminal 0805 (YI201209) ferrite bead: 600 Ω ±25% at 100 MHz, DCR 0.10 Ω max, rated current 2.5 A max. |
| 2 | 2 | passive | Terminal 2 of the two-terminal 0805 (YI201209) ferrite bead: 600 Ω ±25% at 100 MHz, DCR 0.10 Ω max, rated current 2.5 A max; the bead is non-polarised so the terminals are interchangeable. |
