Key electrical parameters include an inductance of 1600 µH, a rated AC voltage of 250 V, and a maximum DC current rating of 1.5 A. The component has a maximum DC resistance of 0.11 Ω and operates within a temperature range of -40 °C to +125 °C. Physical dimensions are approximately 13 mm in length, 9.5 mm in width, and 14 mm in height.

Feature Summary

• Current-compensated ring core design for effective common mode noise suppression
• Ferrite core construction optimized for power line applications
• Radial leaded termination for through-hole PCB mounting

Applications

• Power line filtering in electronic equipment
• Common mode choke applications in AC mains circuits
• EMI suppression in general purpose power supplies

Procurement Notes

Verify the specific suffix N040 against the manufacturer's latest datasheet to confirm pinout and tolerance specifications. Ensure the procurement source provides original TDK/EPCOS documentation to validate RoHS compliance and material composition. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity before finalizing orders.

Selection Notes

Select this component for applications requiring high current compensation and low differential mode inductance. The 1.5 A current rating suits moderate power line filtering needs. Consider the physical footprint constraints as the radial leads require specific PCB spacing. Verify that the 1600 µH inductance meets the target frequency attenuation requirements for the specific EMI profile.

Part Context

This component belongs to the B82720 series of current-compensated ring core chokes from EPCOS. These components are designed for AC power line filtering where common mode interference must be attenuated without introducing significant impedance to the differential signal or power flow. The series offers various inductance values tailored for different current ratings and voltage classes.

Replacement Considerations

Check for direct substitutes within the B82720 series with compatible inductance and current ratings. Verify mechanical compatibility for radial leaded packages. Ensure replacement parts maintain the same ferrite core characteristics and operating temperature range.
