BV301S24012

Overview

The BV301S24012 is a 1.2VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting. It features an EI30 laminated core with a case dimension of 32.8x27.8mm and a maximum height of 22.3mm. The unit operates with a primary input voltage of 115V at 50/60 Hz and provides a secondary output of 24V. The rated secondary current is 50mA. This component utilizes vacuum pressure encapsulation to ensure compactness and efficiency in linear power supply applications.

Feature Summary

• Fully encapsulated under vacuum pressure for enhanced efficiency and compact form factor
• EI30 laminated core construction providing stable magnetic performance
• Through-hole mounting design suitable for standard PCB assembly processes

Applications

• Linear power supply circuits requiring isolated AC-to-AC conversion
• Electronic equipment utilizing 24V secondary control or signal processing stages
• Industrial control systems needing reliable low-voltage isolation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm electrical ratings and mechanical dimensions. Ensure that the required input voltage matches the 115V specification documented for this part number. Cross-reference the secondary current rating of 50mA with the load requirements of the target application to prevent overloading. Confirm that the through-hole package dimensions fit within the designated PCB footprint constraints.

Selection Notes

Select this component when a 1.2VA capacity is sufficient for the intended load while maintaining a low profile. The EI30 core size offers a balance between power density and physical volume. Consider the 115V primary input requirement relative to the available line voltage. The encapsulated construction provides environmental protection compared to open-frame alternatives. Verify compatibility with the target operating frequency range of 50/60 Hz.

Part Context

This transformer belongs to the BV series of encapsulated power transformers manufactured by Zettler Magnetics. The series utilizes laminated cores fully encapsulated under vacuum pressure to achieve smaller sizes and improved efficiency. The BV301S24012 specifically denotes a 1.2VA unit with a 115V primary and 24V secondary output. The 'S' in the model number typically indicates a specific winding configuration or lead arrangement within the series.

Replacement Considerations

Direct substitutes must match the 1.2VA rating, 115V primary, and 24V secondary specifications. Verify that alternative components maintain the same EI30 core type and through-hole mounting style. Check that replacement units offer equivalent encapsulation standards and case dimensions of approximately 32.8x27.8mm. Ensure the secondary current capability meets or exceeds the 50mA requirement.
