Common Mode Chokes Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to procurement, as availability may vary by region. Confirm that the through-hole package dimensions align with the target PCB layout constraints. Ensure the 2A current rating meets the operational requirements of the intended circuit application without exceeding thermal limits.

Common Mode Chokes Selection Notes

Select this component when a 3 mH inductance value is required for common mode noise attenuation in 2A circuits. The 200 mOhm DCR indicates low insertion loss, making it suitable for efficiency-sensitive designs. Consider the 250V AC rating for mains-connected applications. Evaluate the physical size against available board space before finalizing the design.

Common Mode Chokes Part Context

This component belongs to Tamura's series of common mode chokes, which are passive magnetic components used to suppress high-frequency noise on differential lines. These devices typically consist of two windings on a shared core, providing high impedance to common mode signals while allowing differential signals to pass unaffected.

Common Mode Chokes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative manufacturers' offerings based on matching inductance, current rating, and physical footprint specifications.
