POWER INDUCTOR, SHIELDED, 20% TO
Stock Quantity: 0
The XAL1010-222MED from Coilcraft is a shielded power inductor designed for DC-DC conversion and power supply applications. Its construction utilizes a composite core material to achieve a balance between high saturation current and low core loss. The “222” designation indicates a nominal inductance value of 2.2 µH, with a tolerance of ±20%. Electrical characteristics include a specified saturation current (Isat) at which the inductance drops by a defined percentage (typically 10-30%), and an RMS current (Irms) rating based on a specified temperature rise due to power dissipation in the winding resistance (DCR). The shielded construction minimizes electromagnetic interference (EMI). The XAL1010 package refers to its physical dimensions, approximately 10mm x 10mm, and is surface mountable. Detailed specifications for Isat, Irms, DCR, and self-resonant frequency (SRF) are available in the manufacturer’s datasheet.
