Procurement Notes

Verify the specific part number RT8522-12-5M0 against official TE Connectivity / Schaffner documentation to ensure compatibility with your design requirements. Confirm that the 12 A current rating and 5 mH inductance meet your circuit specifications. Check the operating temperature range and physical dimensions for proper fit within your enclosure. Ensure compliance with relevant safety standards for medical or industrial equipment if applicable.

Selection Notes

Select this component when high current capacity and significant common mode noise reduction are required in a vertical PCB layout. Consider the 14 mOhm DCR for efficiency calculations. Evaluate the -30% to +50% inductance tolerance against your EMC filter design margins. Verify that the 300 VDC maximum voltage rating aligns with your system's operational limits.
