Procurement Notes
Verify the specific suffix Y03 against official datasheets to confirm impedance and tolerance specifications. Confirm RoHS compliance status through manufacturer documentation. Ensure PCB footprint matches the 1210 metric package dimensions. Validate thermal performance requirements against the specified operating temperature range before integration.
Selection Notes
Select this component when designing circuits requiring common mode noise attenuation for high-speed serial data lines. The 60 Ohm impedance value targets specific EMI frequencies relevant to USB and FireWire standards. Consider the 250 mA current rating to ensure adequate headroom for signal line bias currents without saturation.
Part Context
This part belongs to the BWCU series of compact common mode chokes from Pulse Electronics. The series offers various impedance values ranging from 25Ω to 2200Ω. These components are engineered for space-constrained portable electronics and high-density PCB layouts requiring effective electromagnetic interference suppression.
Replacement Considerations
Cross-reference with Chilisin CUW11T-600M-N as a potential equivalent based on shared family characteristics. Verify pinout compatibility and mechanical footprint alignment before substitution.
