• High current handling capability up to 6 Amperes
• Low DC resistance to minimize power loss

Common Mode Chokes Applications

• Power line filtering
• Common mode noise suppression
• Signal integrity protection in electronic circuits

Common Mode Chokes Procurement Notes

Verify the specific datasheet version and product change notifications prior to ordering. Confirm that the surface mount package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final application. Check RoHS compliance status if required by project specifications.

Common Mode Chokes Selection Notes

Select this component when high current capacity and low impedance are critical for power line applications. The 96 µH inductance provides effective common mode noise attenuation. Consider the physical size constraints as the toroidal package requires specific clearance on the circuit board. Evaluate thermal performance under continuous load conditions.

Common Mode Chokes Part Context

This part belongs to the PA274xNL series of common mode chokes from Pulse Electronics. These components are designed for surface mount technology and utilize a toroidal magnetic core structure. The series offers various inductance and current ratings to suit different power filtering needs while maintaining a consistent form factor for manufacturing consistency.

Common Mode Chokes Replacement Considerations

PA2745NL: Lower current rating (5A) and higher inductance (130uH). PA2743NL: Significantly lower current rating (3.3A) and higher inductance (383uH). Verify electrical parameters match before substitution.
