Procurement Notes
Verify the specific ordering suffix to confirm compliance requirements. The standard 10M303J designation implies leaded construction. Confirm if RoHS compliance or lead-free status is required for the target assembly by checking for the LF suffix variant. Ensure the axial lead spacing matches the PCB footprint specifications before procurement.
Selection Notes
Select this component when a 300 µH inductance value is required for RF circuits with low current demands up to 46 mA. The unshielded design minimizes cost and size but requires careful layout to prevent magnetic interference with nearby components. Verify that the 27 Ohm DC resistance aligns with the circuit's impedance and power dissipation constraints.
Part Context
Gowanda Electronics specializes in high-performance magnetic components for aerospace, defense, and medical sectors. The 10M series represents their standard line of molded RF coils. These components are engineered for reliability in critical applications where consistent electrical performance is essential.
Replacement Considerations
The 10M303JLF is a lead-free variant of the same electrical specification. Direct substitution requires verifying environmental compliance requirements. No other cross-model replacements are documented in public sources.
