BV301D15028

Overview

The BV301D15028 is a laminated power transformer from the BV series by Zettler Magnetics, designed for through-hole mounting. It features a 115V primary input at 50/60Hz and provides a dual 15V secondary output with a maximum current of 93mA per winding. The unit has a rated power capacity of 2.8VA. Physically, it utilizes an EI30 lamination size with case dimensions of 32.8x27.8mm and a height of 29.8mm. 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 form factor
• Dual secondary windings providing isolated 15V outputs suitable for linear power applications
• Through-hole mounting design compatible with standard PCB assembly processes

Applications

• Linear power supply circuits requiring step-down voltage conversion
• Electronic devices needing UL Class 2 or General-Purpose isolation
• AC input systems operating at 110VAC to 115VAC levels

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm electrical characteristics and mechanical dimensions. Ensure that the selected variant matches the required primary voltage and secondary configuration for the target application. Cross-reference the part number with authorized distributors to confirm availability and authenticity before purchase.

Selection Notes

Select this component when a compact, encapsulated transformer is required for low-power linear applications. The 2.8VA rating and dual 15V output make it suitable for small electronics. Confirm compatibility with the system's input frequency and voltage requirements. Consider the through-hole package constraints during PCB layout design to ensure proper fit within the enclosure.

Part Context

This component belongs to the BV series of encapsulated power transformers from Zettler Magnetics. The series is characterized by vacuum-encapsulated laminated cores designed for smaller, more efficient linear power solutions. These transformers are commonly used in general-purpose and safety-isolated applications, often meeting UL Class 2 standards.

Replacement Considerations

Consult the official Zettler Magnetics cross-reference documentation for verified substitute part numbers. Do not assume interchangeability based on similar VA ratings alone. Verify that any alternative component matches the exact pinout, encapsulation type, and safety certifications required by the original design.
