Procurement Notes
Verify the specific manufacturer source, as this part may be distributed by YAGEO or Pulse Electronics directly. Confirm RoHS compliance status and lead times through authorized distributors. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, to align with assembly requirements.
Selection Notes
Select this component when designing for USB 2.0 or FireWire interfaces requiring 200 Ohm impedance at 100 MHz. It is suitable for space-constrained designs due to its small footprint. Verify that the 330 mA current rating meets the system's operational needs and that the unshielded design does not interfere with nearby sensitive components.
Part Context
This component belongs to the BWCU series of common mode chokes from Pulse Electronics. These devices are engineered for signal integrity in digital communication ports. The series offers various impedance values and current ratings to suit different high-speed bus standards, providing reliable EMI reduction for consumer electronics and industrial equipment.
Replacement Considerations
Check for direct substitutes within the BWCU series with matching 200 Ohm impedance and compatible package dimensions. Ensure any replacement maintains the same current handling capabilities and operating temperature range to guarantee circuit performance equivalence.
