Fixed Inductors Procurement Notes

Verify RoHS compliance status when ordering, as datasheet records indicate variations across the CTS1F series. Confirm specific tolerance codes (J for ±5%) during procurement to ensure alignment with circuit requirements. Check manufacturer documentation for current environmental compliance declarations regarding lead content and hazardous substances.

Fixed Inductors Selection Notes

Select this component for applications requiring shielded axial inductors with precise 820 µH values. Ensure the operating temperature range of -55 °C to 125 °C meets system thermal constraints. Consider the 34 Ohm DC resistance limit for power loss calculations. Verify that the physical package dimensions fit the available PCB real estate.

Fixed Inductors Part Context

This part belongs to the CTS1F series of shielded inductors from Central Technologies. The series includes various inductance values and tolerance options, such as K for ±10%.
