750311898

Overview

The Würth Elektronik 750311898 is a common mode choke from the WE-CMB series, designed for power line interference suppression. It features an inductance of 57 mH at 10 kHz and supports a maximum DC current of 160 mA. The component has a DC resistance of 15.7 Ohms and a self-resonant frequency of 280 kHz. It utilizes a through-hole mounting style with a compact MID-D11 package design.

Feature Summary

• Compact MID-D11 package design for efficient space utilization
• High suppression capability for asymmetric interferences on power lines
• Through-hole construction for robust mechanical attachment

Applications

• Power line filtering in electronic equipment
• Suppression of common mode noise in AC/DC converters
• EMI reduction in industrial control systems

Procurement Notes

Verify the specific datasheet version when ordering, as design changes may occur. Confirm that the through-hole pin configuration matches your PCB layout requirements. Ensure the 160 mA current rating meets the operational demands of your circuit to prevent saturation. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when high inductance is required for low-frequency noise attenuation. The 15.7 Ohm DC resistance impacts power loss; ensure thermal management accounts for I²R losses at full load. Compare the 280 kHz self-resonant frequency against your target noise spectrum to verify effective filtering performance.
