BV301S12012

Overview

The BV301S12012 is a 1.2VA encapsulated power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a single primary winding rated for 115V input at 50/60Hz and a single secondary winding providing 12V output with a maximum current of 100mA. The component utilizes an EI30 lamination size with a case dimension of 32.8x27.8mm and a height of 22.3mm. It offers high isolation voltage capabilities suitable for general-purpose AC-DC power supply applications requiring compact encapsulation.

Feature Summary

• Encapsulated construction for environmental protection and mechanical stability
• Single primary to single secondary winding configuration
• Through-hole PC pin termination for standard PCB integration

Applications

• Low-power AC-DC converter circuits
• Control panel power supplies
• Consumer electronics internal power stages

Procurement Notes

Verify the specific datasheet revision and electrical tolerances against the target design requirements before procurement. Confirm that the 115V primary rating aligns with the local mains frequency and voltage standards. Ensure the 1.2VA power limit accommodates peak load currents without saturation. Check for RoHS compliance status if required by regulatory frameworks.

Selection Notes

Select this model when a compact, encapsulated transformer is needed for 115V to 12V conversion at low current levels. The EI30 core size provides a balance between physical footprint and magnetic performance. Consider the through-hole package constraints regarding PCB layout and spacing requirements compared to surface-mount alternatives.

Part Context

This component belongs to the BV series of encapsulated power transformers from Zettler Magnetics. The series typically includes various VA ratings and voltage configurations, all sharing similar encapsulation techniques and through-hole mounting styles. The BV301S12012 specifically addresses the need for small form-factor isolation in low-power applications.

Replacement Considerations

Direct substitutes may include other 1.2VA encapsulated transformers with identical 115V primary and 12V secondary specifications. Verify pinout compatibility and physical dimensions to ensure board fit. Alternative models within the same manufacturer's line should be cross-referenced for equivalent thermal and electrical performance.
