BV302D18006

Overview

The BV302D18006 is a laminated power transformer from the Zettler Magnetics BV series, designed for through-hole mounting. It features a single primary winding rated for 230V input and a secondary output of 18V at 33mA. The unit has a power rating of 0.6VA and utilizes an EI30 lamination size with a case height of 15.7mm. Dimensions are 32.8mm in length and 27.8mm in width. The transformer is fully encapsulated under vacuum pressure to ensure efficiency and compactness.

Feature Summary

• Fully encapsulated construction under vacuum pressure for enhanced efficiency and compact design
• Through-hole mounting with PC pin termination style
• Single primary winding configuration compatible with standard AC line voltages

Applications

• Linear power supply circuits requiring isolated AC voltage transformation
• Industrial control systems utilizing low-power transformer stages
• Electronic equipment needing encapsulated components for environmental protection

Procurement Notes

Verify that the specific suffix matches the required electrical characteristics, as variations may exist within the BV series. Confirm that the through-hole footprint aligns with the PCB layout requirements. Ensure the 0.6VA power rating meets the load demands of the target circuit. Check datasheet specifications for insulation class and operating temperature range before integration.

Selection Notes

Select this component when a compact, encapsulated transformer is required for low-power applications. The 0.6VA rating suits devices with minimal current draw. Consider the physical dimensions of 32.8x27.8mm for board space constraints. The encapsulation provides robustness against moisture and contaminants, making it suitable for demanding environments compared to non-encapsulated alternatives.

Part Context

This part belongs to the BV series of encased power transformers from Zettler Magnetics. These units are characterized by their vacuum-pressure encapsulation process, which distinguishes them from standard open-frame transformers. The series offers various voltage configurations while maintaining consistent mechanical profiles based on the EI30 lamination size.

Replacement Considerations

Cross-reference with BV302S06006 or BV302D18006-ZU if similar encapsulation and VA ratings are needed. Verify that substitute parts maintain the same 230V primary and 18V secondary specifications. Ensure mechanical compatibility regarding case dimensions and pin spacing before substitution.
