Key Specifications
The HI2220T101R-10 is a surface-mount ferrite chip bead from Laird Performance Materials, part of the HI series designed for high-impedance EMI suppression. Housed in a compact 2220 package (5.7×5.0mm), this component provides a nominal impedance of 100Ω at 100MHz, making it suitable for filtering high-frequency noise in power supply lines, DC-DC converters, and signal circuits.
When selecting this ferrite bead, consider the rated current and DC resistance (DCR) to ensure it meets your circuit's power requirements. The 100Ω impedance at 100MHz is effective for suppressing noise in the 10MHz to 1GHz range (typical for ferrite beads, but verify with frequency-impedance curve). For higher current applications, verify the derating curve. Always refer to the official datasheet for exact specifications and application notes.
