SRF2012-300Y

Overview

The Bourns SRF2012-300Y is a common mode chip inductor from the SRF2012 series, designed for surface mount applications. It features a ferrite core and a four-terminal configuration within a compact 2.0 x 1.2 mm package with a height of 1.1 mm. The component provides a nominal impedance of 30 ohms at 100 MHz and supports a maximum DC current of 450 mA. It exhibits a maximum DC resistance of 500 mΩ ±25% and operates reliably across a temperature range of -55°C to +125°C.

Feature Summary

• Four-terminal surface mount architecture for efficient PCB integration
• Ferrite core construction optimized for high-frequency noise suppression
• Compact low-profile form factor suitable for space-constrained designs

Applications

• Data line filtering in portable electronic devices
• Noise suppression for USB and communication interfaces
• EMI reduction in consumer electronics signal paths

Procurement Notes

Verify availability status as this specific part number may be obsolete or discontinued by the manufacturer. Confirm if the updated suffix variant (SRF2012-300YA) is available as a direct replacement. Ensure compliance with RoHS standards and validate that the supplier provides genuine components with traceable documentation before finalizing procurement.

Selection Notes

Select this component when a 30-ohm impedance at 100 MHz is required for common mode noise attenuation. The 450 mA current rating suits low-power data lines. Consider the SRF2012A series variants for updated manufacturing availability while maintaining similar electrical characteristics and physical dimensions for board-level compatibility.

Part Context

This component belongs to the Bourns SRF2012 series of common mode chokes. These inductors are engineered for suppressing electromagnetic interference in high-speed digital circuits. The series utilizes multilayer technology to achieve consistent performance in small footprints, addressing the growing demand for miniaturized passive components in modern electronics.

Replacement Considerations

The SRF2012-300YA is documented as an available substitute for the SRF2012-300Y. Verify pinout compatibility and electrical equivalence before implementation.
