Fixed Inductors Procurement Notes

Verify the specific manufacturer datasheet for the CTS3F-821K to confirm exact electrical tolerances and thermal ratings. Ensure the procurement specification matches the required 820 µH inductance and 80 mA current rating. Confirm RoHS compliance status if restricted substances are prohibited in the final assembly. Check for any specific ordering suffixes that may alter performance characteristics or packaging methods.

Fixed Inductors Selection Notes

Select this component when a shielded axial inductor is required for general purpose applications. The 820 µH value and 80 mA rating define its operational limits. Consider the 13 Ω DC resistance impact on circuit efficiency. The axial form factor dictates board layout constraints compared to radial or surface mount alternatives. Verify compatibility with the target operating temperature range of -55 °C to 125 °C.

Fixed Inductors Part Context

This part belongs to the CTS3F series of shielded mold inductors from Central Technologies. The series offers various inductance values with consistent axial packaging. The 'K' suffix typically denotes a ±10% tolerance. This specific model provides a high-inductance option within the shielded axial category, distinguishing it from unshielded or lower-inductance variants in the same product line.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 820 µH inductance, 80 mA current rating, and axial shielded form factor. Verify equivalent DC resistance and tolerance specifications. Cross-reference with other manufacturers offering shielded axial inductors with identical pinout and mechanical dimensions.
