Procurement Notes

This component is officially discontinued and no longer manufactured by Taiyo Yuden. Verification of availability should focus on obsolete stock or authorized distributors holding remaining inventory. Buyers must confirm the end-of-life status and ensure that any sourced units are genuine and undamaged. Replacement strategies should be prioritized due to the lack of future production support.

Selection Notes

Selection requires evaluating the specific inductance and current rating needs against the fixed specifications of this discontinued part. Designers must account for the physical dimensions and radial pin configuration during layout planning. Since the part is obsolete, alternative components with similar electrical characteristics and mounting styles should be identified to ensure long-term supply chain stability and design continuity.

Part Context

The TLF24HB series represents Taiyo Yuden's lineup of leaded common mode chokes intended for AC line protection. These components are characterized by their high inductance values and ability to suppress electromagnetic interference in power circuits. The TLF24HB1230R9K1 specifically belongs to this category, offering a standardized solution for noise reduction in applications requiring through-hole assembly and robust performance under varying thermal conditions.

Replacement Considerations

DigiKey lists substitute options for this obsolete product. Engineers should review available alternatives that match the 33 mH inductance, 500 mA current rating, and radial package constraints to maintain circuit functionality.
