Common Mode Chokes Procurement Notes

Verify the specific ordering number against the manufacturer's latest documentation to ensure compatibility with current production requirements. Confirm that the through-hole footprint matches the target PCB layout dimensions prior to procurement. Check for any recent product change notices or end-of-life announcements from SCHURTER Inc. to assess long-term availability risks for ongoing projects.

Common Mode Chokes Selection Notes

Choose this component when a low-profile, magnetically balanced choke is required for single-phase lines carrying up to 1.5A. Ensure the operating voltage does not exceed 440V AC and that the board space accommodates the specified flat dimensions. Validate thermal performance under load conditions to guarantee reliable operation within the designated environmental limits.
