744795080

Overview

The Würth Elektronik 744795080 is a through-hole common mode choke designed for two-line applications. It features an inductance of 80 µH measured at 1 kHz and provides a DC resistance of 60 mΩ per line. The component supports a maximum current rating of 500 mA and exhibits a resistance of 1.34 Ω at 100 MHz. This shielded device utilizes a ferrite core construction suitable for electromagnetic interference suppression in electronic circuits.

Feature Summary

• Provides common mode noise suppression for dual-line configurations
• Utilizes a shielded design to contain magnetic fields
• Constructed with a ferrite core for effective high-frequency attenuation

Applications

• Electromagnetic interference filtering in power supply lines
• Signal integrity protection in data transmission interfaces
• Noise reduction in automotive electronic systems

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturing changes may occur. Confirm that the through-hole package dimensions match the target PCB footprint. Ensure the 500 mA current rating meets the operational requirements of the circuit. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a two-line common mode choke with 80 µH inductance is required for through-hole mounting. The 60 mΩ DC resistance minimizes voltage drop in low-current applications up to 500 mA. Consider the 1.34 Ω impedance at 100 MHz for high-frequency noise profiles. Evaluate thermal performance based on the expected continuous current load within the specified temperature range.
