Fixed Inductors Procurement Notes

Verify the specific suffix 'M' indicates the required 20% tolerance level during procurement. Confirm that the package type matches the intended automated assembly process, as this series is available in cut tape or reel formats. Ensure the thermal management design accounts for the 180°C maximum rating and the specific heating current limits defined in the official datasheet to prevent derating issues.

Fixed Inductors Selection Notes

Select this component when high-temperature stability and compact footprint are critical. The 4.7 µH value suits applications requiring moderate energy storage with low impedance. Compare the 8.5 A saturation current against peak load requirements. Consider the 42 mOhms DCR for efficiency calculations. Verify compatibility with reflow soldering profiles specified for AEC-Q200 components.

Fixed Inductors Part Context

This part belongs to the SRP6030VA series, designed for high-current and high-temperature environments. It complements other variants like the SRP6030VA-150M within the same physical envelope. The series targets automotive and industrial sectors demanding robust magnetic components. It shares the shielded architecture found in the broader SRP family but utilizes ferrite cores distinct from iron powder alternatives.

Fixed Inductors Replacement Considerations

Direct substitutes include other SRP6030VA series parts with identical inductance values. Cross-reference similar shielded SMD inductors from manufacturers offering AEC-Q200 certification. Verify pinout compatibility and thermal characteristics before substitution.
