Procurement Notes
Verify the specific ordering suffix to confirm compliance requirements. The 'LF' designation indicates lead-free status, while other suffixes may denote different material compositions or testing standards. Confirm that the selected variant meets all necessary regulatory certifications for your specific application environment before finalizing procurement.
Selection Notes
Select this component when an unshielded axial inductor is required for RF filtering or tuning. Ensure the circuit operates within the 167 mA current limit to avoid saturation. The 2.85 ohm DC resistance must be accounted for in power loss calculations. Verify that the 12.7 MHz self-resonant frequency aligns with the target signal bandwidth.
Part Context
This part belongs to Gowanda's line of high-performance fixed inductors tailored for demanding environments. The manufacturer specializes in custom and standard magnetic components for critical sectors including aerospace, defense, and medical imaging. These components are engineered to maintain stability under rigorous operational conditions.
Replacement Considerations
Direct substitutes include the 15M512K, which shares identical electrical specifications but may differ in packaging suffixes. Cross-reference datasheets to ensure mechanical dimensions and terminal configurations match the existing board layout before implementation.
