Frequently Asked Questions
What inductance and DCR does the Würth 744823601 provide for common mode EMI filtering at 50 Hz?
The 744823601 common mode choke offers 1000 µH inductance with a maximum DC resistance of 0.013 Ω per winding. At 50 Hz mains frequency, this high inductance effectively attenuates common mode noise on data and power lines, while the low DCR of 0.013 Ω ensures minimal power loss in the filter stage.
How does the dual-function 4-pin configuration of the 744823601 benefit multi-line EMI filter designs?
The 4-pin through-hole package incorporates 2 filter functions in a single component, allowing simultaneous common mode filtering of two signal or power conductors with a single PCB footprint measuring 25 x 17 mm. This reduces BOM count and PCB area compared to using two separate 2-pin chokes in data line filter applications.
In which safety-certified industrial or power distribution applications is the 744823601 most appropriate?
The UL-approved, RoHS-compliant 744823601 is suited for 50 Hz industrial power distribution boards, building automation controllers, motor soft-starters, and wired communication interfaces such as RS-485 or Profibus lines where conducted EMI must meet EN 55011 Class B limits. Its 26.5 mm height supports use in DIN-rail mounted enclosures with standard component clearances.
