Procurement Notes
Verify the specific ordering suffix against official documentation, as variations such as T8114NLT may indicate different packaging formats like cut tape or reel compared to the standard tube configuration. Confirm that the required quantity aligns with manufacturer minimum order quantities and lead times before finalizing procurement plans to ensure supply chain compatibility.
Selection Notes
Select this component when designing circuits requiring 4.7 mH common mode inductance with a 400 mA current rating. Ensure the design accommodates the specified 700 milliohm DC resistance and the physical footprint of 8.90 mm by 6.30 mm. Verify thermal management capabilities meet the -40°C to +85°C operating range requirements for the intended environment.
Part Context
This part belongs to the Pulse Electronics common mode choke family, specifically engineered for EMI suppression in data communication lines. It serves as a passive filter component to mitigate electromagnetic interference in high-speed digital interfaces. The product is classified under signal line filters and is RoHS compliant, adhering to modern environmental standards for electronic components.
Replacement Considerations
Check for compatible substitutes from the same manufacturer series, such as variants with adjusted inductance or current ratings. Ensure any replacement maintains the same surface-mount package dimensions and pin configuration to fit existing PCB layouts without redesign.
