Procurement Notes
Verify the specific suffix Y02 against official datasheets to confirm impedance and tolerance specifications. Confirm RoHS compliance status through manufacturer documentation. Ensure PCB footprint matches the 1.25 x 1 mm outline. Validate thermal performance within the specified operating temperature range during integration.
Selection Notes
Select this component when filtering high-speed serial data requires 330 Ohms impedance at 100 MHz. Consider the 100 mA current rating for circuit compatibility. The unshielded design may influence placement relative to sensitive traces. Verify that the low DC resistance meets voltage drop requirements for the specific application.
Part Context
This part belongs to the BWCU series of compact common mode chokes from Pulse Electronics. These components are engineered for space-constrained portable electronics and high-density PCB layouts. The series offers various impedance values tailored for different signal integrity requirements in digital communication standards.
Replacement Considerations
Cross-reference with other BWCU series variants for different impedance levels. Verify pinout compatibility before substituting. Check if alternative manufacturers offer equivalent 330 Ohm @ 100 MHz specifications in identical package sizes.
