Overview
The BWCU00201212750M02 is an unshielded surface-mount common mode choke manufactured by Pulse Electronics. It features a 75 Ohm impedance with a 20% tolerance, tested at 100 MHz. The component supports a maximum DC current of 250 mA and has a maximum DC resistance of 300 mOhms. It operates within a temperature range of -40°C to +105°C. The physical dimensions are 2.0 mm in length, 1.2 mm in width, and 1.2 mm in height. It utilizes SMD/SMT termination for PCB mounting.
Feature Summary
- Designed for noise suppression in high-speed digital interfaces
- Compact surface-mount form factor for space-constrained layouts
- Unshielded construction suitable for general EMI filtering
Applications
- USB 2.0 data line protection
- IEEE 1394b (FireWire) signal integrity
- LVDS interface filtering
Procurement Notes
Verify the specific manufacturer designation, as documentation references Chilisin components under the Pulse Electronics branding. Confirm RoHS compliance status through official datasheets prior to integration. Ensure the ordering suffix matches the required packaging format, typically tape and reel, for automated assembly processes.
Selection Notes
Select this component when designing circuits requiring common mode noise attenuation for USB or FireWire standards. The 75 Ohm impedance value is critical for maintaining signal integrity in these specific protocols. Consider the 250 mA current rating to ensure the choke does not saturate during peak operational loads.
Part Context
This part belongs to the BWCU series of SMD common mode chokes. These components are categorized under Inductors, Chokes & Coils. The series is specifically engineered for protecting sensitive data lines against electromagnetic interference in consumer electronics and computer peripherals.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative CMCs based on impedance, current rating, and package dimensions before substitution.
