SMRF5025-912J

Fixed Inductors Overview

The SMRF5025-912J is a fixed surface-mount RF inductor from the Gowanda Electronics SMRF5025 series. It features an unshielded molded construction with iron core material. The component provides a nominal inductance of 91 µH and supports a maximum DC current rating of 254 mA. Its maximum DC resistance is specified at 5.3 Ohms. The device utilizes a non-standard footprint configuration suitable for compact electronic designs.

Fixed Inductors Feature Summary

• Unshielded molded construction for specific electromagnetic interference requirements
• Surface mount technology integration for automated assembly processes
• Iron core material selection for stable RF performance characteristics

Fixed Inductors Applications

• Radio frequency circuit filtering applications
• General purpose signal processing stages
• Compact electronic module integration

Fixed Inductors Procurement Notes

Verify the exact suffix designation during procurement, as 'J' indicates tolerance while 'LF' denotes lead-free status. Confirm that the non-standard footprint matches the target PCB layout constraints. Ensure the 5.3 Ohm DC resistance aligns with power loss specifications. Validate that the unshielded design does not interfere with adjacent sensitive components in the final assembly.

Fixed Inductors Selection Notes

Select this component when an unshielded form factor is required to minimize physical height or cost. The 91 µH value suits mid-range RF filtering needs. Consider the 254 mA current limit for power handling requirements. The non-standard package necessitates custom footprint verification before finalizing the design.

Fixed Inductors Part Context

This part belongs to the SMRF5025 series of molded unshielded surface mount RF inductors. The series offers a broad inductance range from 1.0 µH to 22,000 µH. Gowanda Electronics manufactures these components for demanding industrial and commercial applications requiring reliable magnetic performance.

Fixed Inductors Replacement Considerations

Cross-reference with other SMRF5025 series variants such as SMRF5025-912JLF for lead-free compliance. Verify equivalent inductance and current ratings against alternative unshielded molded inductors from different manufacturers if supply constraints exist.
