SRR4528A-101M

Fixed Inductors Overview

The Bourns SRR4528A-101M is a shielded surface-mount power inductor from the SRR4528A series. It features a fixed inductance of 100 µH with a tolerance of ±20%. The component has a maximum RMS current rating of 560 mA and a maximum DC resistance of 609 mΩ. Its self-resonant frequency is specified at 24 MHz, tested at 100 kHz. The device utilizes a nonstandard corner terminal configuration for mounting.

Fixed Inductors Feature Summary

• Shielded construction to minimize electromagnetic interference
• Nonstandard corner terminal design for specific footprint requirements
• Suitable for space-constrained portable electronics applications

Fixed Inductors Applications

• Portable electronic devices
• General-purpose power supply circuits
• DC-DC converter stages

Fixed Inductors Procurement Notes

Verify the specific package dimensions against the PCB footprint, as this component uses a nonstandard corner terminal configuration rather than standard end terminals. Confirm that the 560 mA RMS current rating meets the application's continuous load requirements. Ensure the 100 µH inductance value aligns with the circuit design specifications before integration.

Fixed Inductors Selection Notes

Select this component when a shielded inductor is required for compact designs. The nonstandard corner terminals necessitate careful layout planning. Consider the 609 mΩ DC resistance impact on efficiency. Verify availability of compatible footprints if replacing standard terminal components. Check thermal performance under full load conditions.

Fixed Inductors Part Context

This part belongs to the SRR4528A series of shielded power inductors manufactured by Bourns Inc. The series is designed for surface-mount technology applications. Other variants in the series offer different inductance values and current ratings while maintaining similar physical constraints and shielding characteristics.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 100 µH inductance, 560 mA current rating, and 609 mΩ resistance. Due to the nonstandard corner terminal design, mechanical compatibility is critical. Verify that alternative components support the same self-resonant frequency and operating temperature range.
