Overview
The Würth Elektronik 750314976 is a through-hole common mode choke from the MID-DC16US series, utilizing an EE16.5/6.5/9 core. It provides 3.3 mH inductance at 10 kHz with a current rating of 2 A and low DC resistance of 164 mOhm. Designed for reliable operation in noise suppression applications, it supports high-frequency filtering requirements.
Feature Summary
- Through-hole mounting configuration for robust PCB integration
- High inductance value effective for common mode noise suppression
- Low DC resistance to minimize power loss in signal lines
Applications
- Common mode noise filtering in data lines
- EMI suppression in industrial control systems
- Signal integrity protection in communication interfaces
Procurement Notes
Verify the specific suffix code against the manufacturer datasheet to confirm exact electrical tolerances and core material specifications. Ensure the through-hole footprint matches the EE16.5/6.5/9 mechanical drawing dimensions before finalizing design integration.
Selection Notes
Select this component when through-hole assembly is required for mechanical stability in noisy environments. The 2 A rating suits moderate current applications, while the 3.3 mH inductance targets lower frequency interference compared to surface mount alternatives.
Part Context
Part of the MID-DC16US series, designed for general electronic equipment noise suppression. Manufactured by Würth Elektronik, a German provider of electronic components known for innovative magnetic solutions and high-quality standards in industrial and consumer markets.
Replacement Considerations
Check equivalent EE16.5/6.5/9 core chokes from other manufacturers. Verify identical inductance (3.3 mH), current rating (2 A), and DCR (164 mOhm) to ensure functional compatibility without redesigning the PCB footprint.
FAQ
What is the inductance tolerance for the 750314976?
The datasheet specifies the nominal inductance as 3.3 mH at 10 kHz; consult the official specification sheet for the exact manufacturing tolerance percentage.
Is this component suitable for high-frequency switching power supplies?
It is designed for common mode noise suppression rather than energy storage in switching converters. Its 164 mOhm DCR and 2 A rating define its operational limits for line filtering.
