SRF1006-102Y

Overview

The Bourns SRF1006-102Y is a surface-mount common mode choke designed for EMI suppression in high-speed data lines. It features a dual-line configuration with an inductance of 1 mH at 100 kHz and an impedance of 1.4 kOhms at 1 MHz. The component supports a maximum DC current of 520 mA and operates within a voltage rating of 50 VDC. It exhibits a low DC resistance of 180 mOhms and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Dual-line architecture for effective common mode noise attenuation
• Compact surface-mount footprint suitable for space-constrained PCB layouts
• Low DC resistance minimizes signal loss and power dissipation
• Robust thermal stability for demanding operating environments

Applications

• High-speed data line filtering
• USB interface protection
• Ethernet port noise suppression
• General purpose EMI mitigation in consumer electronics

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm packaging and tolerance specifications. Ensure compatibility with automated pick-and-place equipment regarding the surface-mount package dimensions. Cross-reference the impedance and inductance values with the target circuit requirements to validate performance at the intended operating frequency.

Selection Notes

Select this component when designing circuits requiring moderate inductance for common mode noise reduction on differential pairs. The 520 mA current rating suits low-power data interfaces rather than high-current power lines. Consider the 180 mOhm DC resistance impact on signal integrity for long trace applications. Evaluate the physical size constraints against available board real estate.

Part Context

This part belongs to the Bourns SRF1006 series of surface-mount common mode chokes. The series offers various inductance values tailored for different frequency suppression needs. These components are engineered for reliability in commercial and industrial electronic assemblies, providing consistent performance across the specified temperature range.

Replacement Considerations

Consult the official Bourns datasheet for direct pin-compatible alternatives within the SRF1006 series. Verify that any substitute maintains identical impedance characteristics at 1 MHz and meets the 520 mA current requirement. Ensure the replacement part shares the same package dimensions and mounting style.
