BV301S12023

Overview

The BV301S12023 is a single-phase power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features an EI30 laminated core and encapsulated construction. The unit operates at 50/60Hz with a 115V primary input voltage and provides a 12V secondary output capable of delivering 192mA. The device has a rated power capacity of 2.3VA and offers 4200Vrms isolation voltage. Physical dimensions are 32.80mm in length, 27.80mm in width, and a maximum seated height of 29.50mm.

Feature Summary

• Encapsulated construction for environmental protection
• Through-hole PC pin termination style
• High isolation voltage rating of 4200Vrms

Applications

• General purpose AC to DC power supply circuits
• Low power electronic equipment requiring isolated power
• Control transformers for small signal applications

Procurement Notes

Verify the specific part number suffix against official Zettler Magnetics documentation to ensure correct voltage and current ratings. Confirm that the through-hole mounting type matches your PCB design requirements. Check datasheets for thermal derating curves if operating near the 2.3VA limit. Ensure compliance with regional safety standards required for the final assembly.

Selection Notes

Select this component when a compact, encapsulated transformer is needed for low-power applications. The 115V primary input suits regions using standard North American or similar electrical grids. Consider the physical footprint of 32.80mm x 27.80mm for board space constraints. Verify that the 12V output meets the load requirements of the downstream circuitry.

Part Context

This model belongs to the BV301 series from Zettler Magnetics, utilizing EI30 lamination sizes. It is distinct from other variants in the series such as the BV301S15023, which may have different output specifications. The series is characterized by fully loaded single-phase configurations suitable for general industrial and commercial electronics.

Replacement Considerations

Direct substitutes within the same series include models like BV301S15023, though output parameters differ. Cross-referencing with other manufacturers requires matching VA rating, isolation voltage, and physical dimensions. Always verify pinout compatibility before swapping components.
