Fixed Inductors Procurement Notes
Verify the specific suffix (e.g., LF) against the datasheet to confirm RoHS compliance status. Ensure the ordering code matches the required tolerance and current ratings. Confirm package dimensions align with PCB footprint requirements before finalizing procurement orders.
Fixed Inductors Selection Notes
Select this component when a compact surface-mount inductor with high Q-factor is needed for RF applications. Consider the 635 mA current limit and 240 mΩ DCR for power loss calculations. Verify that the 235 MHz self-resonant frequency suits the target signal bandwidth.
Fixed Inductors Part Context
This part belongs to the SMRF series of standard RF inductors from Gowanda Electronics. These components are designed as chip inductors for surface mounting. The series offers various inductance values while maintaining consistent physical dimensions and electrical characteristics for standardized design integration.
Fixed Inductors Replacement Considerations
Cross-reference with other Gowanda SMRF series parts for different inductance values. Verify mechanical compatibility with existing footprints. Check if alternative manufacturers offer equivalent 390 nH SMD inductors with matching current and frequency specs.
