03DKBW5B

Overview

The Delta Electronics 03DKBW5B is a general-purpose, single-phase power line filter designed for chassis mounting. It provides electromagnetic interference (EMI) suppression for AC power lines with a rated voltage of 250VAC and a continuous current capacity of 3A. The component utilizes wire-to-wire connections to attenuate conducted noise in electrical circuits.

Feature Summary

• Provides EMI filtering for single-phase AC power applications
• Designed for secure chassis mounting installation
• Supports standard wire-to-wire termination methods

Applications

• General electronic equipment power input stages
• Industrial control systems requiring noise suppression
• Consumer appliances connected to AC mains

Procurement Notes

Verify the specific datasheet version for the 03DKBW5B to confirm exact attenuation curves and safety certifications such as UL or VDE. Ensure the mounting hardware matches the chassis specifications. Confirm that the 3A rating aligns with the system's maximum load requirements under all operating conditions.

Selection Notes

Select this component when a compact, single-stage EMI filter is required for 250VAC circuits. The 3A current rating suits low-power applications. Consider thermal derating if ambient temperatures exceed standard limits. Verify physical dimensions against available chassis space before integration.

Part Context

This part belongs to Delta Electronics' passive component portfolio, specifically within their power line filter series. These components are engineered to meet international EMC standards for conducted emissions. The manufacturer focuses on reliability and consistent performance across industrial and commercial environments.

Replacement Considerations

Check for direct substitutes with identical 250VAC/3A ratings and compatible mounting styles. Ensure replacement filters maintain similar insertion loss characteristics at target frequencies. Verify that alternative parts hold the same safety approvals required by the end application.
