Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Central Technologies documentation to ensure authenticity. Confirm that the J-Lead package style matches your PCB footprint requirements. Check that the 12 µH inductance value and 155 mA current rating align with your circuit design constraints. Ensure the ±10% tolerance meets your system's precision needs. Validate the operating temperature range covers your intended environmental conditions.

Fixed Inductors Selection Notes

Select this component when an unshielded SMD inductor with J-Leads is required for space-constrained designs. Consider the 2.7 Ω DC resistance impact on power efficiency. Evaluate the 40 MHz self-resonant frequency limit for high-frequency operation. Ensure the 155 mA current handling capacity suffices for the application load. Verify compatibility with standard reflow soldering profiles for J-Lead packages.
