SRF0504-351Y

Overview

The Bourns SRF0504-351Y is a surface-mount common mode choke designed for signal line filtering. It features an inductance of 1.1 µH with a tolerance of ±35% and a maximum DC current rating of 2 A. The component exhibits a maximum DC resistance of 40 mΩ and operates within a frequency range of 55–900 MHz. It utilizes ferrite core material and is housed in a 0504 (1210 metric) package measuring 5 mm x 4.8 mm x 4.8 mm. The device supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference suppression for high-speed data lines
• Utilizes ferrite core technology for stable performance across wide frequency ranges
• Designed for compact surface-mount integration on printed circuit boards

Applications

• EMI suppression in high-speed digital interfaces
• Signal line filtering for USB and HDMI applications
• Noise reduction in telecommunications equipment

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's official documentation to confirm compliance with RoHS directives and lead-free requirements. Ensure that the requested quantity aligns with standard factory packaging specifications, typically provided in reels or cut tape formats, to avoid discrepancies during procurement processing.

Selection Notes

Select this component when a 1.1 µH inductance value is required for common mode noise attenuation. Consider the 2 A current rating and low DC resistance for power integrity. Evaluate the 0504 footprint constraints against available PCB space. Confirm that the 55–900 MHz operational range matches the target signal frequencies for effective filtering.

Part Context

This part belongs to the SRF0504 series of line filters manufactured by Bourns. The series offers various inductance values ranging from 0.60 µH to 6.0 µH, all sharing similar physical dimensions and mounting characteristics. This specific model represents a mid-range inductance option within the family, balancing impedance and current handling capabilities.

Replacement Considerations

Direct substitutes within the same series include SRF0504-102Y and SRF0504-152Y, which offer different inductance values but maintain identical package dimensions and electrical interface standards.
