Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status through the provided datasheet or certification documents. Ensure the procurement channel sources genuine components from authorized distributors to guarantee authenticity and traceability.
Selection Notes
Select this component when designing for automotive environments requiring high thermal stability and compact form factors. The 320 mA rating suits low-current signal lines, while the 220 Ohm impedance targets specific frequency ranges. Verify that the 3.2x1.6mm footprint aligns with the target PCB layout constraints and that the unshielded design meets the system's EMI requirements.
Part Context
This part belongs to the AWCU series of common mode chokes from Pulse Electronics. These components are engineered for surface-mount technology and are specifically tailored for automotive-grade reliability. The series emphasizes small footprints suitable for dense circuit board designs while maintaining robust electrical performance under varying thermal conditions.
Replacement Considerations
Cross-reference with other AWCU series variants for different impedance values. Verify compatibility with alternative suppliers offering equivalent AEC-Q200 qualified automotive chokes in the same 3216 package size.
