Overview
The BWCU00252012801Y3P is a surface-mount common mode choke manufactured by Pulse Electronics. It provides an impedance of 800 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 150 mA and features a DC resistance (DCR) of 1.6 Ohms. Rated for a maximum voltage of 50 VDC, it operates within a temperature range of -40°C to +105°C. The physical package dimensions are 2.5 mm in length, 2 mm in width, and 1.2 mm in height.
Feature Summary
- Designed for high-impedance noise suppression in differential signal lines
- Compact surface-mount form factor suitable for space-constrained PCB layouts
- Unshielded construction optimized for specific EMI filtering requirements
Applications
- USB 2.0 interface protection
- IEEE 1394b (FireWire) data line filtering
- LVDS signal integrity enhancement
Procurement Notes
Verify the exact impedance value and DCR specifications against the official manufacturer datasheet prior to procurement. Confirm that the 150 mA current rating aligns with the target circuit's operational requirements. Ensure the 50 VDC voltage rating meets the system's electrical isolation needs. Cross-reference the package dimensions to validate PCB footprint compatibility during the design phase.
Selection Notes
Select this component when designing circuits requiring significant common mode noise attenuation at 100 MHz. The 800 Ohm impedance level is suitable for suppressing high-frequency interference on sensitive digital interfaces. Consider the 1.6 Ohm DCR impact on signal loss if low insertion loss is critical. The unshielded design may require careful layout consideration to minimize radiated emissions from the component itself.
Part Context
This part belongs to the BWCU series of compact common mode chokes from Pulse Electronics. The series offers a wide impedance range from 25 Ohms to 2200 Ohms, allowing designers to tailor EMI suppression levels. These components are specifically engineered for high-density applications where small footprints are required without compromising filtering performance.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative components by matching impedance, current rating, and package dimensions.
