Additional Details

The '2R2M' designates an inductance of 2.2 μH with a tolerance of ±20%. Saturation current (Isat) and rated current (Irms) are crucial parameters for proper operation; refer to the datasheet for specific values and ensure they are not exceeded in your application. The 'T04' likely indicates a specific taping or packaging configuration. Always consult the official TDK datasheet for detailed electrical specifications, temperature derating curves, and recommended soldering profiles. Proper PCB layout is critical for minimizing parasitic inductance and capacitance, which can negatively impact the inductor's performance. Consider using a multilayer PCB with a dedicated ground plane to improve EMI shielding.
