BV301S15012

Overview

The BV301S15012 is a 1.2VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting. It features an EI30 laminated core and operates with a 115V primary input to provide a 15V secondary output at 80mA. The unit measures 32.8x27.8mm with a maximum height of 22.3mm. Fully encapsulated under vacuum pressure, it ensures compactness and efficiency for linear power supply applications.

Feature Summary

• Fully encapsulated construction under vacuum pressure for enhanced reliability
• EI30 laminated core design for efficient magnetic coupling
• Through-hole mounting configuration for standard PCB integration

Applications

• Linear power supply circuits
• Low-power electronic equipment requiring isolated AC voltage conversion
• Control transformers in compact enclosures

Procurement Notes

Verify the specific part number BV301S15012 against official Zettler Magnetics documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with 115V primary systems and 15V secondary requirements. Check for any ordering suffixes that may indicate variations in lead times or packaging, as these do not alter functional specifications. Confirm through-hole pin spacing matches target PCB layout.

Selection Notes

Select this component when a compact, low-power (1.2VA) isolated transformer is required for 115V to 15V conversion. The EI30 core size suits space-constrained designs. Verify that the 80mA secondary current meets load demands. Consider thermal management within the encapsulated housing. Ensure the operating frequency aligns with standard mains frequencies unless otherwise specified in detailed datasheets.

Part Context

This transformer belongs to the BV series of encapsulated power transformers by Zettler Magnetics. The series utilizes EI30 laminations and offers various voltage configurations. The BV301S15012 specifically denotes the 15V secondary variant within this family, sharing common mechanical and encapsulation traits with other models like the BV301S18012.

Replacement Considerations

Direct substitutes include other BV301S150xx variants with identical VA ratings and core sizes but different secondary voltages if circuit topology allows. Cross-reference with Zettler's official replacement guides for equivalent performance in terms of encapsulation and mounting.
