XAL4020-222MEC Pinout

Package: SMD, 4×4 mm (Shielded Power Inductor)

Notes

• XAL4020-222MEC is a shielded power inductor with 2.2 µH nominal inductance (±20%).
• This is a two-terminal surface-mount component; pin numbering follows standard SMD conventions (typically pin 1 and pin 2 on opposite corners or edges of the 4×4 mm package).
• Electrical specifications at 25°C:
  • Inductance: 2.2 µH ±20%
  • DCR (typ/max): 35.20 / 38.70 mOhms
  • SRF (typ): 52 MHz
  • I_sat: 5.6 A
  • I_rms (20°C rise / 40°C rise): 4.0 A / 5.5 A
• Height: 0.083 in / 2.1 mm max
• Weight: 0.17–0.18 g
• The datasheet does not provide a detailed pin diagram with numbered pads for this inductor family; the two-terminal configuration is standard for all XAL40xx variants.
