BV202D18005

Overview

The BV202D18005 is a laminated power transformer from the Zettler Magnetics BV series, designed for through-hole mounting. It features a 230V primary input and dual 18V secondary outputs, delivering a total power rating of 0.5VA with 13.9mA per secondary winding. The unit utilizes PC pin termination and measures 24.0mm in length, 23.0mm in width, and 19.5mm in height. Fully encapsulated under vacuum pressure, it ensures electrical isolation and mechanical stability for linear power supply applications.

Feature Summary

• Fully encapsulated construction under vacuum pressure for enhanced efficiency and compactness
• Dual secondary windings providing isolated output channels
• Through-hole mounting with PC pin termination for secure board integration

Applications

• Linear power supply circuits requiring low voltage AC outputs
• Electronic equipment needing isolated 18VAC secondary rails
• Control systems utilizing standard 230VAC mains input

Procurement Notes

Verify the specific secondary voltage configuration (dual 18V) against circuit requirements before procurement. Confirm that the through-hole PC pin pitch matches the target PCB layout dimensions. Ensure the 0.5VA power rating suffices for the intended load current to prevent thermal overload during operation.

Selection Notes

Select this component when a compact, encapsulated transformer with dual isolated secondaries is required for 230VAC input systems. The BV series offers a balance of size and performance suitable for space-constrained designs. Consider the physical dimensions of 24.0mm x 23.0mm x 19.5mm to ensure adequate clearance on the assembly board.

Part Context

This part belongs to the BV series of encapsulated power transformers by Zettler Magnetics. The series utilizes EE20 laminations and is designed for high reliability in consumer and industrial electronics. The BV202D18005 specifically denotes the 230V primary variant with dual 18V secondaries within this standardized product line.

Replacement Considerations

Check datasheets for alternative models in the BV series with identical VA ratings and pin configurations. Verify that any substitute maintains the same encapsulation type and through-hole mounting style to ensure mechanical compatibility without redesigning the PCB footprint.
