It features an inductance of 6.8 mH at 10 kHz and supports a current rating of 1.3 A with two lines. The component has a DC resistance of 0.314 ohms ±10% and utilizes an EE16.5/6.5/9 core structure.

Feature Summary

• Suppresses common-mode noise in power electronics applications
• Through-hole mounting for robust mechanical connection
• Dual-line configuration for balanced signal integrity

Applications

• Power supply input filtering
• DC-DC converter noise reduction
• Industrial control system EMI suppression

Procurement Notes

Verify the specific package type and lead configuration against the official datasheet before integration. Confirm that the 1.3 A current rating meets the operational requirements of the target circuit. Ensure compatibility with automated or manual assembly processes due to the through-hole design.

Selection Notes

Select this component when high inductance is required for low-frequency noise attenuation. The through-hole format is suitable for applications requiring higher mechanical stability compared to surface-mount alternatives. Evaluate thermal performance under continuous load conditions to ensure reliability within the operating temperature range.

Part Context

This part belongs to the WE-CMB series of common mode chokes by Würth Elektronik. These components are engineered for effective electromagnetic interference suppression in power circuits. The series offers various inductance values and current ratings to suit different power electronics designs.

Replacement Considerations

Check for direct substitutes with identical inductance (6.8 mH) and current rating (1.3 A). Verify pin compatibility and physical dimensions if space constraints exist. Consider alternative manufacturers offering similar EE-core through-hole chokes with comparable electrical specifications.
