Application Scenarios & Design Considerations

Inductors for Power Circuits Wound Ferrite SLFseries

Alternative Part Number

  • CDRH127/LD-4R7NC --: Shielded power inductor with similar 4.7 uH inductance and comparable current rating, different series naming makes it easy to distinguish from the source.
  • SRR1260-4R7Y --: Shielded SMD power inductor with 4.7 uH value and similar size class, widely available alternative from a different manufacturer and series.
  • IHLP2525CZER4R7M01 --: Low-profile shielded IHLP series inductor with 4.7 uH inductance and comparable current handling, a common cross-reference for TDK SLF-type parts.
