Procurement Notes
Verify the specific datasheet version for the 15M333K, as Gowanda's product lines often include lead-free (LF) variants. Confirm that the non-LF designation matches project requirements regarding RoHS compliance and soldering profiles. Ensure the surface-mount package dimensions align with the intended PCB footprint design.
Selection Notes
Select this component when a compact surface-mount RF inductor is required for frequencies around 7.9 MHz. Consider the 33 µH value and 2.8 Ω DC resistance against circuit impedance needs. Evaluate the -55°C to +105°C operating range against environmental conditions. Compare physical dimensions against available board space constraints.
Part Context
This part belongs to Gowanda's RF SMT Molded Inductor series, which provides compact solutions for modern electronic assemblies. The series is engineered for reliable performance in high-frequency applications across aerospace, defense, and medical industries. These components utilize specialized molding techniques to ensure durability and consistent electrical characteristics.
FAQ
What is the test frequency for the inductance specification?
The inductance is tested at 7.9 MHz.
Is this component RoHS compliant?
The base model 15M333K is not explicitly designated as lead-free; verify if the LF suffix variant is required for compliance.
