Fixed Inductors Procurement Notes

Verify the specific manufacturer datasheet for the CHNR1050-470M-00000 to confirm exact electrical tolerances and thermal characteristics before integration. Ensure that the surface mount footprint matches the PCB layout requirements. Cross-reference the saturation current and DC resistance values against the system's maximum load conditions to prevent performance degradation under operational stress.

Fixed Inductors Selection Notes

Select this component when a 47 µH inductance value is required with a 2 A saturation current limit. The 10mm x 10mm surface mount package suits designs needing moderate current handling in a compact form factor. Consider the 163 mOhm DC resistance for efficiency calculations in low-voltage applications. Verify compatibility with standard reflow soldering profiles for surface mount technology.

Fixed Inductors Part Context

This part belongs to the CHNR series of fixed inductors from Chipsen, which includes various inductance values and current ratings. The series utilizes wirewound technology for stable performance. Similar models in the lineup offer different inductance values such as 33 µH or 151 µH, maintaining consistent packaging dimensions for design flexibility across different power stages.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 47 µH inductance, 2 A saturation current, and 10x10 mm surface mount footprint. Verify equivalent DC resistance and shielding characteristics to ensure identical electromagnetic performance. Check for compatible operating temperature ranges and mounting configurations.
