SRF0602-181Y

Overview

The Bourns SRF0602-181Y is a surface mount common mode choke from the SRF0602 series, designed for high-frequency noise suppression. It features an inductance of 180 µH with a tolerance of ±50% and a DC current rating of 300 mA. The component exhibits a DC resistance of 0.25 Ω and provides an impedance of 500 Ω at 3 MHz. Its compact physical dimensions are 6.5 mm x 3.6 mm x 1.65 mm, suitable for space-constrained PCB layouts.

Feature Summary

• Surface mount construction for automated assembly
• Dual-line common mode filtering capability
• High impedance performance at 3 MHz

Applications

• Data line protection
• Signal integrity enhancement
• EMI suppression in compact electronics

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm lead-free status and RoHS compliance. Ensure the 180 µH inductance value matches the circuit requirements, as the series offers a wide range from 10 to 330 µH. Confirm that the 300 mA current rating is sufficient for the intended application to prevent saturation.

Selection Notes

Select this component when a low-profile, dual-line filter is required for frequencies between 3 and 250 MHz. The 180 µH value is appropriate for moderate noise environments where higher inductance is unnecessary. Consider the 0.25 Ω DCR for power loss calculations in sensitive signal paths.

Part Context

This part belongs to the SRF0602 series of SMD common mode chokes by Bourns Inc. The series is characterized by its small footprint and broad inductance options, targeting applications requiring effective EMI reduction without occupying significant board space.

Replacement Considerations

Consult the official Bourns SRF0602 datasheet for direct cross-references. Verify that any substitute maintains the 180 µH inductance, 300 mA rating, and compatible package dimensions.
