Overview
The SRF0504A-102Y is a surface-mount common mode choke from the Bourns SRF0504 series, designed for noise suppression in data and signal lines. It features an inductance of 2.7 uH with a tolerance of 30% and a rated current of 1.5 A. The component exhibits a maximum DC resistance of 60 mOhms and an impedance of 1 kOhm at 100 kHz. Operating within a temperature range of -40 C to +125 C, it utilizes a ferrite core and is housed in a compact 0504 (1210 metric) package measuring 5 mm x 5.2 mm x 4.8 mm.
Feature Summary
- Provides effective common mode noise attenuation for high-speed data and signal transmission lines.
- Utilizes a ferrite core material to ensure stable magnetic performance across the specified operating temperature range.
- Designed for space-constrained applications through its low-profile surface-mount construction.
Applications
- Noise suppression in USB interface circuits
- Signal line filtering in portable electronic devices
- EMI reduction in compact consumer electronics
Procurement Notes
Verify the specific suffix 'A' against the manufacturer's official documentation to confirm physical dimensions and electrical characteristics match project requirements. Ensure compatibility with standard reflow soldering profiles for SMD components. Confirm RoHS compliance status via the latest datasheet revision before finalizing procurement specifications.
Selection Notes
Select this component when designing circuits requiring common mode filtering with limited board space. The 1.5 A current rating suits moderate power signal lines. Evaluate the 2.7 uH inductance value against target frequency attenuation needs. Consider the 60 mOhms DCR impact on signal integrity and voltage drop in the specific application circuit.
Part Context
This part belongs to the SRF0504 series of line filters manufactured by Bourns Electronic Solutions. The series offers various inductance values in a standardized small outline package. These components are engineered for general-purpose EMI suppression in digital and analog signal paths where size constraints limit the use of larger through-hole or standard SMD chokes.
Replacement Considerations
Cross-reference with other SRF0504 series variants for different inductance values. Verify pinout and footprint compatibility with existing PCB layouts before substituting. Consult official Bourns documentation for direct equivalent part numbers if specific electrical parameters differ.
