The component supports a current rating of 1.3A and operates within a temperature range of -40°C to +105°C. Its physical dimensions are 2.29 mm in length, 1.52 mm in width, and 1.2 mm in height. Designed for SMD/SMT PCB mounting, it utilizes an unshielded configuration suitable for signal line filtering applications.
Feature Summary
- Designed specifically for two-line data transmission and power delivery circuits
- Provides enhanced noise immunity for sensitive signal lines
- Constructed as an unshielded surface-mount device for compact integration
Applications
- USB 2.0 interface protection
- IEEE 1394b (FireWire) signal filtering
- LVDS (Low-Voltage Differential Signaling) circuit noise suppression
Procurement Notes
Verify the specific impedance value against project requirements, as datasheets may list variations such as 120 Ohms or 30 Ohms for similar part numbers. Confirm the current rating aligns with the target circuit load. Ensure the manufacturer designation matches the intended supply chain source, as branding discrepancies can occur between distributors and original equipment manufacturers.
Selection Notes
Select this component for applications requiring common mode noise reduction in differential data lines. The low profile and small footprint make it suitable for space-constrained designs. Evaluate the operating temperature range to ensure compatibility with the environmental conditions of the final assembly. Consider the unshielded nature when assessing electromagnetic interference susceptibility in dense layouts.
Part Context
This component belongs to the BWCU series of common mode chokes produced by Pulse Electronics. The series is engineered for high-performance signal integrity in digital communication interfaces. These components serve as critical passive elements for maintaining signal quality in high-speed data transmission environments.
Replacement Considerations
The part number alias CUW0805-121M-N is documented for related models in the series. Verify electrical parameters such as impedance and current rating before substituting with other common mode chokes from different manufacturers.
