03DKBG5B

Overview

The Delta Electronics 03DKBG5B is a single-phase general-purpose EMI/EMC line filter designed for AC power line noise suppression. It operates at frequencies of 50Hz and 60Hz with a rated voltage of 115VAC or 250VAC and a continuous current rating of 3A. The component utilizes chassis mounting with quick-connect tab terminals for secure installation. Key electrical specifications include a maximum leakage current of 2.0mA at 250VAC 50Hz (with 10,000pF) and a hipot rating of 2250VDC line-to-ground. Physical dimensions are approximately 75.9mm in length, 51.8mm in width, and 29.5mm in height.

Feature Summary

• Provides effective suppression of both line-to-line and line-to-ground electromagnetic interference noise.
• Features UL recognition, CSA certification, and VDE approval for global compliance.
• Utilizes a flange mount design with quick-connect terminals for straightforward integration.

Applications

• Single-phase electronic equipment requiring EMI filtering
• Industrial control systems operating on 115VAC or 250VAC lines
• General-purpose power supplies needing EMC compliance

Procurement Notes

Verify the specific ordering suffix to ensure correct terminal configuration and mounting style compatibility with your enclosure design. Confirm that the 3A current rating and 250VAC voltage limit align with your system's operational requirements. Check for updated certification marks such as UL, CSA, and VDE status before finalizing procurement to meet regional regulatory standards.

Selection Notes

Select this component when a single-phase filter with a 3A capacity is required for chassis-mounted applications. Ensure the available space accommodates the specified physical dimensions of 75.9mm x 51.8mm x 29.5mm. Verify that the quick-connect tab terminals match the wiring harness or PCB footprint used in the target assembly.

Part Context

This part belongs to Delta Electronics' general-purpose single-phase EMI filter series, which includes variants with different current ratings and capacitance values. The series is engineered to help designers reduce electromagnetic interference in AC power lines, facilitating faster product development and market entry while ensuring compliance with international EMC standards.

Replacement Considerations

Consult official Delta Electronics documentation for direct cross-references within the 03DK series. Verify that any substitute maintains identical current, voltage, and dimensional specifications to ensure mechanical and electrical compatibility without redesigning the host enclosure.
