• Sealed construction protects internal windings from environmental factors
• Through-hole mounting facilitates secure PCB integration

Applications

• Consumer electronics power supplies
• Industrial control systems
• Low-power supply applications requiring voltage conversion

Procurement Notes

Verify the specific part number BV201S09003A against official Zettler Magnetics documentation to confirm electrical ratings and mechanical dimensions. Ensure compatibility with existing PCB layouts regarding through-hole spacing and clearance requirements. Check for any updated regulatory compliance certifications relevant to your region before finalizing procurement decisions.

Selection Notes

Select this component when a compact, low-power transformer is needed for 115V AC input applications. The 0.35VA rating suits devices with minimal power consumption needs. Consider the 2800 Vrms isolation rating for safety-critical designs. Verify that the 16mm height fits within the enclosure constraints of the target product assembly.

Part Context

This model belongs to the BV201 series of power transformers from Zettler Magnetics. The series typically includes variants with different secondary voltages, such as BV201S06003A and BV201S12003A, sharing similar form factors and core designs. These components are engineered for general-purpose power conversion in space-constrained electronic devices.

Replacement Considerations

Direct substitutes may include other models from the BV201 series with matching VA ratings and isolation levels, provided the secondary voltage matches the application requirement. Cross-referencing mechanical dimensions is essential to ensure fitment on the existing PCB footprint.
