SRF0502-102Y

Overview

The Bourns SRF0502-102Y is a shielded common mode choke from the SRF0502 series, designed for surface mount PCB assembly. It features a compact 5 mm x 5 mm footprint with a low profile height of 2.5 mm. The component provides an inductance of 2.5 µH and exhibits an impedance of 1 kΩ at 100 MHz. It supports a maximum DC current rating of 2 A with a maximum DC resistance of 45 mΩ. The device operates within a temperature range of -40°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Low-profile 2.5 mm height suitable for space-constrained designs
• AEC-Q200 qualified for automotive reliability standards

Applications

• EMI suppression in automotive electronic systems
• Signal integrity protection in high-speed data lines
• Power line filtering in DC-DC converter circuits

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm packaging configuration and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit. Cross-reference the AEC-Q200 certification status if automotive compliance is mandatory for the end product.

Selection Notes

Select this component when a shielded common mode choke with a 2.5 µH inductance and 2 A current rating is required. The 5x5x2.5 mm package is appropriate for applications needing low-profile EMI filtering. Consider the 1 kΩ impedance at 100 MHz for high-frequency noise attenuation requirements in sensitive signal or power lines.

Part Context

This part belongs to the Bourns SRF0502 series of surface mount common mode chokes. The series offers various inductance and impedance values within a standardized 5x5 mm footprint. The SRF0502-102Y specifically targets applications requiring moderate inductance with high current handling capabilities in a compact form factor.

Replacement Considerations

Consult the official Bourns SRF0502 series datasheet for direct pin-compatible alternatives with similar electrical characteristics. Verify that any substitute maintains the same 2.5 mm height and AEC-Q200 qualification if automotive use is intended.
