Procurement Notes

Verify the specific suffix K1 against official Taiyo Yuden documentation to confirm packaging and compliance details. Confirm availability status as distribution channels may list discontinued or obsolete inventory. Ensure the procurement source provides valid traceability data matching the manufacturer's original specifications before finalizing orders.

Selection Notes

Select this component when designing single-phase AC filters requiring 2200 µH inductance and 1.2 A current handling. Evaluate thermal management requirements given the 105 °C maximum operating limit. Compare physical footprint constraints against the 17x22 mm case size to ensure compatibility with the target PCB or chassis mounting layout.

Part Context

This part belongs to the TLF series of leaded common mode chokes intended for AC line noise reduction. It serves as a passive filtering solution within power supply stages. The series emphasizes robust construction for mains frequency applications, distinguishing it from surface-mount variants used in low-voltage digital circuits.
