Fixed Inductors Procurement Notes

Verify the specific suffix 'V' indicates vertical mounting orientation as per manufacturer documentation. Confirm that the 150 µH value aligns with circuit requirements, noting the ±15% tolerance. Ensure the 3.3 A current rating meets peak load demands without saturation. Check RoHS compliance status if required by project specifications. Validate lead dimensions against PCB footprint constraints prior to ordering.

Fixed Inductors Selection Notes

Select this component when high thermal stability is critical, given the 150°C operating limit. The shielded construction makes it suitable for noise-sensitive applications compared to unshielded alternatives. Consider the radial form factor for space-constrained vertical layouts. Compare the 110 mΩ resistance against efficiency targets. Evaluate the 3.3 A saturation current against system peak loads to prevent performance degradation under heavy duty cycles.

Fixed Inductors Part Context

This part belongs to Bourns' 2100HT series of high-temperature toroidal inductors. The series is engineered for robust performance in industrial and automotive-grade environments where standard components may fail due to heat. The 2100HT line offers various inductance values and current ratings within the same physical family, allowing designers to scale current handling while maintaining consistent mounting characteristics.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include 2100HT-101-V-RC (100 µH) and 2100HT-221-V-RC (220 µH), provided current and inductance requirements are adjusted accordingly. Cross-series replacements require careful verification of temperature ratings and shielding effectiveness to ensure equivalent performance in the target application.
