BV302D12020

Power Transformers Overview

The BV302D12020 is a 2VA encapsulated power transformer manufactured by Zettler Magnetics. It features a 230V primary winding and dual 12V secondary windings, providing a total output current of 83mA per secondary. Designed for through-hole mounting, this component utilizes an EI30 laminated core with case dimensions of 32.8x27.8mm and a height of 27.4mm. It operates at standard frequencies of 50/60Hz and complies with RoHS standards.

Power Transformers Feature Summary

• Encapsulated construction for environmental protection
• Dual isolated secondary windings for split-rail applications
• Through-hole mounting configuration for PCB integration

Power Transformers Applications

• Low-power AC-DC power supply units
• Control circuit isolation
• Consumer electronics internal power distribution

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm insulation class and safety certifications required for your target market. Ensure the PCB footprint matches the 32.8x27.8mm case dimensions. Confirm that the 230V input rating aligns with your regional mains voltage standards before integration into the final design.

Power Transformers Selection Notes

Select this model when a compact, encapsulated solution is needed for low-power isolation tasks. The dual 12V outputs are suitable for circuits requiring symmetric positive and negative rails. Consider the 2VA power limit to ensure the load does not exceed the 83mA per secondary specification during peak operation.

Power Transformers Part Context

This component belongs to the BV Series of encapsulated power transformers from Zettler Magnetics. The series offers various VA ratings and winding configurations within a standardized EI30 core format. These transformers are designed for general-purpose isolation in small form-factor electronic devices where space constraints and thermal management are critical factors.

Power Transformers Replacement Considerations

Cross-reference part numbers such as BV302D15020 or BV302D09020 if different secondary voltages are required while maintaining the same physical footprint and primary specifications. Verify electrical compatibility before substitution.
