BV201S12003A

Overview

The BV201S12003A is a 0.35VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting. It features a single primary winding rated for 115V input and a single secondary winding providing 12V output at a maximum current of 29mA. The unit utilizes an EE20 lamination size with a case dimension of 23.0x24.0mm and a height of 16.0mm. This component is fully encapsulated under vacuum pressure to ensure efficiency and compactness.

Feature Summary

• Fully encapsulated construction under vacuum pressure for enhanced efficiency
• Single-phase configuration suitable for linear power supply applications
• Through-hole mounting style with PC pin termination

Applications

• Linear power supply circuits
• Low-power electronic device isolation
• Control circuit voltage transformation

Procurement Notes

Verify the specific part number BV201S12003A against official Zettler Magnetics documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with the target PCB layout regarding through-hole spacing and enclosure constraints. Cross-reference datasheet specifications for insulation requirements and thermal performance before integration into the final design.

Selection Notes

Select this transformer when a compact, encapsulated solution is required for low-power 115V to 12V conversion. The 0.35VA rating limits its use to low-current applications requiring approximately 29mA on the secondary side. Consider the EE20 core size and 16.0mm height for mechanical fit within the intended chassis or assembly space.

Part Context

This component belongs to the BV Series of encapsulated power transformers manufactured by Zettler Magnetics. The series is characterized by vacuum-encapsulated laminated cores designed for smaller form factors. The BV201S12003A specifically denotes the 12V secondary variant within this lineup, sharing common structural features with other models in the BV family.

Replacement Considerations

Direct substitutes include other BV series variants such as BV201S10003A or BV201S09003A if different secondary voltages are acceptable. Verify that any replacement maintains the same 0.35VA power rating, 115V primary input, and through-hole mounting compatibility.
