MMZ1005Y400CT000

TDK · Ferrite Beads · 0402

MMZ1005Y400CT000 from TDK, in a 0402. 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 chip bead (40 Ω ±25% at 100 MHz, 0.10 Ω max DC resistance, 550 mA max rated current); the bead is non-polarized so terminals are interchangeable.
2 2 passive Terminal 2 of the two-terminal chip bead (40 Ω ±25% at 100 MHz, 0.10 Ω max DC resistance, 550 mA max rated current); the bead is non-polarized so terminals are interchangeable.
