SRF1006-502Y

Overview

The Bourns SRF1006-502Y is a shielded common mode choke designed for surface mount PCB assembly. It features a ferrite core and operates within a temperature range of -40°C to +105°C. Key electrical parameters include an inductance of 5 mH at 100 kHz, an impedance of 5 kOhms at 500 kHz, and a maximum DC current rating of 250 mA. The component has a maximum DC resistance of 620 mOhm and utilizes a compact 10.00 mm x 8.70 mm footprint with a maximum height of 6.50 mm.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Ferrite core material supports high-frequency noise suppression
• Surface mount design facilitates automated PCB integration

Applications

• EMI suppression on power or data lines
• Signal line filtering in electronic circuits

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the manufacturer's official datasheet prior to ordering. Confirm that the package dimensions and pin configuration align with the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final application. Cross-reference the RoHS compliance status with current regulatory standards.

Selection Notes

Select this component when a compact, shielded common mode choke is required for low-current signal or power line applications. The 250 mA current rating suits sensitive circuitry rather than high-power distribution. Evaluate the 5 kOhm impedance at 500 kHz to ensure adequate attenuation for the targeted noise frequencies. Consider the physical size constraints relative to other available packages in the series.

Part Context

This part belongs to the SRF1006 series of line filters manufactured by Bourns. The series includes various inductance and impedance variants tailored for different EMI suppression needs. These components are categorized under common mode chokes and are intended for use in environments requiring reliable noise reduction in compact form factors.

Replacement Considerations

Compatible substitutes within the same series include SRF1006-402Y and SRF1006-121Y. Verify that alternative part numbers match the required inductance, impedance, and current ratings before substitution.
