Procurement Notes

Verify the specific ordering suffix against the latest TDK Electronics catalog to ensure compatibility with required tolerance and packaging specifications. Confirm that the radial lead configuration matches the target PCB layout requirements. Check for any recent updates to the RoHS compliance status or material declarations prior to final procurement authorization.

Selection Notes

Select this component when a high-inductance value of 47 mH is required for power line filtering with a current capacity of 0.5 A. Ensure the operating environment stays within the -40 °C to +125 °C range. Consider the physical footprint of 23.3 x 16.1 x 25.4 mm for mechanical clearance. This part is suitable for applications needing robust common mode noise attenuation in AC power inputs.
