BV302D06018

Overview

The BV302D06018 is a 1.8VA encapsulated power transformer from Zettler Magnetics' BV series, designed for through-hole mounting. It features a 230V primary input and a single 6V secondary output capable of delivering 150mA. The unit utilizes an EI30 lamination size with a maximum case height of 24.4mm and dimensions of 32.8x27.8mm. Electrical specifications include a primary-to-secondary isolation voltage rating of 1500VAC and a leakage inductance of 24.4mH maximum at 1kHz. The device operates within a temperature range supporting Class B insulation.

Feature Summary

• Encapsulated construction provides environmental protection and mechanical stability for reliable operation.
• Through-hole pin configuration facilitates direct integration into standard printed circuit board assemblies.
• EI30 core geometry ensures efficient magnetic coupling within a compact physical footprint.

Applications

• LED lighting systems requiring isolated low-voltage DC power
• Electric metering devices needing compact step-down transformation
• Motor control circuits utilizing small form-factor transformers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact electrical tolerances and insulation class ratings. Ensure the procurement documentation matches the required lead time and packaging format specified by authorized distributors. Cross-reference the part number with the latest revision history to avoid obsolete inventory acquisition.

Selection Notes

Select this component when a 1.8VA capacity meets the load requirements of the target application. Confirm that the 230V primary voltage aligns with the available AC supply network. Evaluate the 6V secondary output against the downstream circuit's voltage tolerance and current draw needs to ensure adequate performance margins.

Part Context

This transformer belongs to the BV series of encapsulated power transformers, which are engineered for off-line and switch-mode power source applications. The series addresses stringent design requirements for industrial and consumer electronics, offering a balance of performance and reliability through standardized encapsulation techniques and robust core materials.

Replacement Considerations

The BV302D06015 serves as a functional substitute within the same series, differing primarily in its 1.5VA power rating and 6V dual-output configuration. Verify that the lower VA rating and distinct winding structure do not compromise the thermal or electrical integrity of the existing design before implementation.
