BV302S12015

Overview

The BV302S12015 is a 1.5VA power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a single primary winding rated for 230V input and a single secondary winding providing 12V output at 125mA. The unit utilizes an EI 30-12.5 core construction and offers a dielectric strength of 4.2kV with an insulation resistance of 100MOhm. Operating within a temperature class of Ta 70/B, this component supports 50/60 Hz frequencies and complies with RoHS3 standards.

Feature Summary

• EI 30-12.5 laminated core construction for efficient magnetic coupling
• High dielectric isolation capability of 4.2kV for safety compliance
• Through-hole PC pin termination for reliable board integration

Applications

• General purpose AC to DC power supply circuits
• Industrial control system power distribution
• Consumer electronics internal power stages

Procurement Notes

Verify the specific suffix designation against the manufacturer datasheet to confirm encapsulation type and terminal configuration. Ensure the procurement order matches the required voltage ratings and current capacity for the target application circuit. Confirm RoHS3 compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this model when a compact 1.5VA isolation transformer is required for 230V mains applications. The EI core design suits standard through-hole PCB layouts where space constraints allow for its physical dimensions. Consider the 125mA secondary current limit when designing downstream regulation stages to prevent saturation or overheating during peak loads.

Part Context

This component belongs to the BV302S series of encapsulated power transformers from Zettler Magnetics. The series provides various voltage configurations optimized for general industrial and commercial applications. The BV302S12015 specifically addresses needs for 230V primary to 12V secondary conversion in compact form factors.

Replacement Considerations

Cross-reference with BV302S10015, BV302S06015, and BV302S09015 for alternative voltage outputs within the same series. Verify mechanical footprint compatibility before substituting with other manufacturers' EI 30-12.5 core transformers.
