Procurement Notes

Verify the specific manufacturer part number against official datasheets to ensure compatibility with design requirements. Confirm that the encapsulated type matches the thermal and mechanical needs of the target application. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this transformer when a low-power, encapsulated solution is required for isolated power supply stages. Ensure the 9V secondary output aligns with downstream circuitry needs. Consider the through-hole mounting requirement and verify that the physical footprint fits within the available PCB area without interfering with adjacent components.

Part Context

This component belongs to the BV series of encapsulated power transformers from Zettler Magnetics. These products are engineered for off-line and SMPS power sources, offering robust performance in industrial and consumer applications. The series emphasizes reliability and compliance with stringent design requirements for magnetic components.

Replacement Considerations

Direct substitutes may include other BV series variants with matching VA ratings and voltage configurations. Verify pinout compatibility and encapsulation type before substitution. Consult manufacturer cross-reference guides for approved equivalent parts.
