• Two-line configuration for balanced common mode filtering
• Through-hole construction for secure PCB integration

Common Mode Chokes Applications

• Industrial power supply input filtering
• Motor drive EMI suppression
• High-current DC/DC converter stages

Common Mode Chokes Procurement Notes

Verify the specific datasheet version for the DLFP-0147-35C5 to confirm mechanical dimensions and pinout compatibility with your PCB layout. Ensure that the thermal management strategy accounts for the 35A current rating and associated I²R losses at maximum operating temperatures. Cross-reference the 440V AC rating against your system's peak voltage requirements to ensure adequate safety margins under all load conditions.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring robust common mode noise attenuation in high-current environments. The low DC resistance minimizes power loss compared to non-saturating alternatives, while the saturating characteristic allows for compact size without sacrificing current handling capability. Confirm that the through-hole package fits the assembly constraints and that the operating temperature range aligns with the environmental conditions of the final enclosure.

Common Mode Chokes Part Context

This part belongs to Schurter's DLFP series of saturation chokes, which are engineered for demanding power electronics applications. These components are designed to handle significant current loads while maintaining effective electromagnetic interference suppression characteristics. The series is commonly utilized in industrial and automotive sectors where reliability under high stress is critical.

Common Mode Chokes Replacement Considerations

Consult Schurter official documentation for direct cross-references. Verify that any substitute maintains the 35A current rating, 5.3mOhm DCR, and 440V AC rating. Ensure the replacement also supports the -25°C to 100°C operating range and matches the physical footprint for through-hole mounting.
