SRF1006-472Y

Overview

The Bourns SRF1006-472Y is a surface-mount common mode filter choke designed for signal line applications. It features an inductance of 4.7 mH with a tolerance of ±40% and offers an impedance of 6.2 kOhms at 600 kHz. The component supports a maximum DC current of 250 mA and has a maximum DC resistance of 1 Ohm. It operates within a temperature range of -40°C to +105°C and utilizes a compact 10 mm x 8.7 mm x 6.5 mm package.

Feature Summary

• Provides effective common mode noise suppression for dual-line signal circuits
• Designed for surface-mount PCB integration to save space
• Capable of handling high-frequency interference up to 600 kHz

Applications

• Industrial equipment signal filtering
• Audio and video signal line protection
• Consumer electronics noise reduction
• Computer peripheral interface filtering

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's latest datasheet to confirm packaging details, as suffixes often denote reel or cut-tape variations rather than functional changes. Ensure the required operating temperature range aligns with the component's specified limits. Cross-reference the impedance and inductance values with the target circuit design requirements before finalizing procurement decisions.

Selection Notes

Select this component when a compact solution is needed for attenuating common mode noise on low-current signal lines. The 4.7 mH inductance provides significant attenuation at higher frequencies while maintaining a low DC resistance profile suitable for sensitive data transmission paths. Consider the physical dimensions and mounting style compatibility with the printed circuit board layout constraints.

Part Context

This part belongs to the Bourns SRF1006 series of line filters, which are engineered for general-purpose EMI suppression in small form-factor designs. The series offers various inductance values to suit different frequency response needs while maintaining consistent physical footprints for standardized manufacturing processes across multiple product lines.

Replacement Considerations

Consult official substitution guides for compatible parts within the same series or equivalent offerings from other manufacturers that match the 4.7 mH inductance and 250 mA current rating specifications.
