7448263505

Overview

The Würth Elektronik 7448263505 is a leaded common mode choke from the WE-CMB series, designed for high-current applications. It features a ferrite core and wirewound construction within an XXL type housing. Key electrical parameters include an inductance of 500 µH, a maximum DC current rating of 35 A, and a maximum DC resistance of 2.3 mΩ. The component operates within a temperature range of -40°C to +125°C and exhibits a self-resonant frequency of up to 100 kHz.

Feature Summary

• High current handling capability suitable for power line filtering
• Shielded design to minimize electromagnetic interference
• Robust through-hole construction for secure PCB mounting

Applications

• Power supply input filtering
• DC-DC converter EMI suppression
• Industrial equipment noise reduction

Procurement Notes

Verify the specific package dimensions and terminal configuration against your PCB footprint requirements before ordering. Confirm that the 35 A current rating aligns with your system's peak load conditions. Ensure the 500 µH inductance value meets your circuit's impedance specifications at the target operating frequency. Check compliance documentation for regional regulatory standards applicable to your deployment environment.

Selection Notes

Select this component when high current capacity and low DC resistance are critical for minimizing power loss in power lines. The through-hole format is preferred for applications requiring mechanical stability under high stress. Consider the physical size constraints of the XXL housing during layout planning. Evaluate thermal management needs given the high current ratings and potential heat dissipation characteristics of the ferrite core material.
