Overview
The Bourns SRF0504-102Y is a surface-mount common mode choke from the SRF0504 series, designed for line filtering applications. It features an inductance of 2.7 µH with a tolerance of 30% and a rated DC current of 1.5 A. The component exhibits a maximum DC resistance of 60 mΩ and offers an impedance of 1 kΩ 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 4.7 mm.
Feature Summary
- Utilizes a ferrite core material for effective common mode noise suppression
- Designed for surface mount PCB integration with dual-line configuration
- Capable of handling high DC currents while maintaining low series resistance
Applications
- High-speed data line filtering
- USB interface noise suppression
- General purpose EMI/RFI mitigation in consumer electronics
Procurement Notes
Verify the specific suffix 'Y' against the manufacturer's latest datasheet to confirm compliance with RoHS directives and halogen-free status. Ensure the ordering part number matches the required inductance value of 2.7 µH and current rating of 1.5 A. Confirm that the 0504 package dimensions align with the target PCB footprint design rules before finalizing procurement orders.
Selection Notes
Select this component when a compact form factor is required for high-current applications up to 1.5 A. The 2.7 µH inductance provides a balance between signal integrity and noise attenuation for moderate frequency ranges. Consider the 1 kΩ impedance specification for compatibility with the target noise spectrum. The wide operating temperature range supports deployment in environments subject to thermal variation.
Part Context
This component belongs to the Bourns SRF0504 series of surface-mount common mode chokes. The series offers various inductance values tailored for different filtering requirements. The SRF0504-102Y specifically targets applications requiring robust performance in a small footprint, leveraging the standard 0504 package dimensions widely used in modern electronics manufacturing.
Replacement Considerations
Cross-reference other SRF0504 series variants such as SRF0504-152Y or SRF0504-351Y if different inductance or current ratings are needed. Verify pinout compatibility and physical dimensions before substituting with components from other manufacturers.
