Overview
The Würth Elektronik 750311899 is a through-hole common mode choke designed for noise suppression in electronic circuits. It features an inductance of 140 mH at 10 kHz and supports a maximum DC current of 90 mA. The component exhibits a maximum DC resistance of 39 Ohms and operates within a temperature range up to +125°C. Its physical dimensions are 15.75 mm in length, with a vertical package configuration utilizing four PC pins. This part is RoHS3 compliant and classified under ECCN EAR99.
Feature Summary
- Provides effective common mode noise filtering for two-line configurations
- Utilizes a vertical through-hole mounting style for secure board attachment
- Maintains stable electrical performance across a wide operating temperature range
Applications
- Noise suppression in low-current signal lines
- EMI filtering in industrial control systems
- Common mode interference reduction in communication interfaces
Procurement Notes
Verify the specific package type and pin configuration against your PCB footprint requirements before ordering. Confirm that the 90 mA current rating meets your circuit's operational needs. Ensure compatibility with your assembly process for through-hole components. Check for any recent product change notices regarding material or dimensional updates.
Selection Notes
Select this component when high inductance is required for low-frequency noise attenuation in through-hole designs. Consider the 39 Ohm DC resistance impact on signal integrity. Evaluate the 15.75 mm length for spatial constraints on the printed circuit board. Compare against surface-mount alternatives if space is limited.
Part Context
This component belongs to the common mode choke category from Würth Elektronik. It serves as a passive filter element to suppress electromagnetic interference. The part is distinct from inductors and transformers, focusing specifically on differential mode rejection. It is suitable for applications requiring robust noise immunity in compact layouts.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing designs by matching inductance, current rating, and physical dimensions before considering alternative manufacturers.
