SRF2012-670Y

Overview

The SRF2012-670Y is a surface-mount common mode choke manufactured by Bourns Inc. It features two lines of operation with an impedance of 67 Ohms at 100 MHz. The component supports a maximum current rating of 400mA and has a maximum DC resistance (DCR) of 250mOhm. It operates within a temperature range of -40°C to 125°C and utilizes ferrite core material.

Feature Summary

• Provides common mode noise suppression for data lines
• Utilizes ferrite core material for effective filtering
• Designed for surface mount assembly

Applications

• Data line filtering
• Common mode noise suppression in electronic circuits

Procurement Notes

Verify the specific suffix 'YA' or 'Y' against the manufacturer's official documentation, as these may indicate distinct packaging or compliance variations. Confirm RoHS compliance status directly from the source datasheet. Ensure the ordering part number matches the required impedance and current ratings precisely to avoid functional mismatches in the final design.

Selection Notes

Select this component when a low-profile surface-mount solution is required for high-frequency noise attenuation. The 67 Ohm impedance at 100 MHz makes it suitable for specific data line applications. Verify that the 400mA current rating meets the operational requirements of the circuit to prevent saturation or excessive heating during normal use.

Part Context

This component belongs to the SRF series of common mode chokes from Bourns. These devices are engineered for compact electronic designs requiring efficient electromagnetic interference reduction. The SRF2012 designation indicates the physical package size, while the numerical suffix specifies the impedance characteristics relative to frequency.

Replacement Considerations

Direct substitutes include other Bourns SRF series components with matching impedance and current ratings, such as the SRF2012-671YA. Cross-reference specifications carefully to ensure compatibility with existing board layouts and electrical requirements.
