04NB3

Overview

The Delta Electronics 04NB3 is a compact AC power entry module featuring an integrated IEC filter. It supports a rated voltage of 250VAC and a current rating of 4A. The device utilizes snap-in mounting for secure installation. It is designed for single-phase applications and includes N/A-lug termination options. The unit complies with RoHS standards and is classified under ECCN EAR99.

Feature Summary

• Integrated EMI filtering within a compact form factor
• Snap-in mounting mechanism for simplified assembly
• Single-phase AC power entry design

Applications

• Industrial equipment power input stages
• Medical device power supply interfaces
• Consumer electronics AC inlet modules

Procurement Notes

Verify the specific datasheet version for the 04NB3 model to confirm mechanical dimensions and certification marks. Ensure compatibility with the target chassis cutout size for snap-in installation. Check for any regional regulatory requirements regarding AC power entry modules in the destination market. Confirm that the 4A current rating meets the system's maximum load requirements.

Selection Notes

Select this component when a low-profile, filtered AC inlet is required for space-constrained designs. The 4A rating suits moderate power applications. Consider the snap-in feature if through-hole soldering is undesirable. Verify that the internal filter characteristics align with the electromagnetic interference suppression needs of the final product.

Part Context

This part belongs to Delta Electronics' series of compact IEC connector filters. Similar models in the series include the 03NB3, 06NB3, and 10NB3, which vary primarily by current rating. These components are standard solutions for integrating safety and filtering into AC power cords or panels.

Replacement Considerations

Direct substitutes may include other 4A snap-in IEC filters from manufacturers like Amphenol or C&K. Ensure the replacement matches the 250VAC rating and physical snap-in footprint. Verify that the EMI attenuation performance is equivalent to maintain compliance.
