Applications

• Power supply input filtering
• Industrial equipment electromagnetic interference suppression
• Automotive electronics noise reduction

Procurement Notes

Verify the specific manufacturer source, as EPCOS operations are integrated into TDK Electronics. Confirm that the ordering suffix N040 corresponds to the required packaging configuration. Ensure the requested quantity aligns with standard distribution availability. Cross-reference the datasheet specifications against your circuit requirements before finalizing the purchase order.

Selection Notes

Select this component when high current capacity is required alongside common mode noise attenuation. The 54 A rating suits heavy-duty power lines. Verify that the physical dimensions fit the available board space. Consider the wide inductance tolerance if precise filtering characteristics are critical for the target application.

Part Context

This component belongs to the EPCOS/TDK power line choke family. These chokes are engineered for general-purpose electromagnetic compatibility tasks. The product line emphasizes reliability in demanding environments. Integration into modern electronic systems requires adherence to thermal and electrical limits defined in the official documentation.

Replacement Considerations

Consult official TDK cross-reference lists for verified substitutes. Generic equivalents may not match the specific ring core geometry or current compensation characteristics. Ensure any replacement maintains the same voltage and current ratings.
