Procurement Notes
Verify the specific impedance tolerance and current rating requirements against the official datasheet before procurement. Confirm that the surface mount footprint matches the target PCB design. Ensure compatibility with reflow soldering profiles specified by the manufacturer. Cross-reference the part number with authorized distributors to confirm authenticity and availability status.
Selection Notes
Select this component when designing circuits requiring common mode noise suppression for low-current differential signals. The 260 Ohm impedance at 100 MHz makes it suitable for high-frequency applications. Consider the 310 mA current limit to ensure reliable operation under expected load conditions. Evaluate the physical dimensions to ensure adequate clearance on the printed circuit board.
Part Context
This component is part of Pulse Electronics' AWCU series of common mode chokes. These devices are engineered for compact electronic designs where space is limited. The series offers various impedance values to suit different frequency ranges and signal types. They are widely used in consumer electronics and industrial equipment for EMI mitigation.
Replacement Considerations
Check for direct substitutes within the AWCU series with similar impedance and current ratings. Verify pinout compatibility if replacing with components from other manufacturers. Ensure that any alternative part meets the same thermal and electrical performance standards required by the original design.
