- Low DC resistance of 0.125 Ω minimizing insertion loss and power dissipation in filtered signal paths
- Dual-function (2 winding) data line filter configuration supporting differential and common-mode EMI suppression
- Through-hole mounting with compact 23 × 13 × 28 mm body for reliable PCB anchoring in industrial enclosures
- UL approved and RoHS/REACH compliant meeting North American and international safety standards
Applications
The Würth Elektronik 744823210 is used as a data line filter in industrial Ethernet interfaces, RS-485/RS-422 communication buses, and field device I/O modules where common-mode EMI suppression on signal lines is required to meet EMC emission and immunity standards. Its 10000 µH inductance and 2 A current rating make it suitable for protecting serial data ports in PLCs, motor drives, and power converters from high-frequency interference up to several MHz.

Frequently Asked Questions
What inductance and current rating does the Würth 744823210 provide for data line EMI filtering?
The 744823210 offers 10000 µH (10 mH) inductance with a 2 A rated current, enabling effective suppression of common-mode noise on data lines at frequencies from tens of kHz to several MHz. Its 0.125 Ω DC resistance keeps resistive power loss under 0.5 W at full load current.
Which communication bus interfaces benefit most from the 744823210 data line filter?
The 744823210 is well-suited for RS-485, RS-422, CAN bus, and industrial Ethernet data lines where common-mode EMI from nearby motor drives, switching power supplies, or relay switching can disrupt serial communication. Its 10000 µH dual-winding filter provides over 40 dB of common-mode attenuation in the 100 kHz to 10 MHz frequency range.
What are the physical dimensions and mounting type of the 744823210, and how does it fit on a PCB?
The 744823210 measures 23.0 mm × 13.0 mm × 28.0 mm and uses through-hole PCB mounting. Its 4-pin through-hole footprint requires a PCB keep-out area of approximately 23 × 13 mm plus lead clearance, and allows wave or selective soldering. The 28 mm component height must be considered for enclosure clearance in industrial control panel designs.
Does the 744823210 hold UL approval, and what certifications does it carry for industrial deployments?
Yes, the 744823210 carries UL approval for use in safety-rated North American industrial equipment, and is also RoHS and REACH compliant for global environmental compliance. This dual certification profile makes it suitable for industrial automation, building control, and energy management applications where both UL listing and EU environmental directives are required.
