760806400

Overview

The Würth Elektronik 760806400 is a shielded radial leaded power inductor from the WE-PFC series, designed for Power Factor Correction (PFC) applications. It features an inductance of 180 µH with a tolerance of ±10%. The component supports a rated current of 3 A at a temperature rise of 40 K and handles a maximum DC current of 13.2 A. Its maximum DC resistance is 200 mΩ. Operating within a temperature range of -40°C to +85°C, it utilizes a standard PCB mount style with dimensions of 32 mm height.

Feature Summary

• Shielded construction minimizes electromagnetic interference in dense circuit layouts
• Optimized for critical conduction mode PFC topologies
• Radial through-hole termination facilitates manual assembly and prototyping

Applications

• Power factor correction chokes for AC-DC converters
• Critical conduction mode (CRM) PFC circuits
• Intermittent conduction mode (DCM) power supplies

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to ordering, as environmental certifications may vary by production batch. Confirm that the 13.2 A maximum DC current rating aligns with your thermal management strategy, as this value differs from the 3 A rated current used for inductance stability calculations. Ensure the 200 mΩ DCR specification meets your efficiency requirements.

Selection Notes

Select this component when designing PFC stages requiring high saturation current capability alongside stable inductance under load. The 180 µH value is suitable for medium-power applications operating in CRM or DCM modes. Consider the 32 mm height constraint for enclosure design. The shielded design is preferred where magnetic coupling with nearby components must be avoided, unlike unshielded alternatives in the same series.

Part Context

This part belongs to the WE-PFC series, which specializes in chokes for power factor correction. Unlike general-purpose inductors, these are engineered specifically for the high-current, high-frequency switching environments typical of PFC front-ends. The series includes various inductance values tailored to different power levels and controller ICs, such as those from onsemi.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate other WE-PFC variants based on inductance and current ratings if this specific value is unavailable.
