Procurement Notes

Verify the specific ordering suffix matches the required secondary voltage tolerance and current rating. Confirm that the encapsulation type aligns with thermal management requirements. Ensure the through-hole pin spacing corresponds to the target PCB footprint. Check for any regional safety certification marks required for the final assembly destination. Validate input voltage compatibility with the local mains frequency.

Selection Notes

Select this component when a compact 1.2VA transformer is needed for 230V input systems requiring dual 15V outputs. Consider the EI30 core size constraints and 22.3mm height limit during mechanical design. Evaluate the 40mA per secondary limit against peak load currents. Ensure the operating temperature range accommodates the ambient environment. Compare isolation voltage requirements against system safety standards.

Part Context

This part belongs to the BV series of encapsulated power transformers by Zettler Magnetics. The series typically utilizes EI30 laminations and offers various voltage configurations. It is positioned as a general-purpose solution for low-voltage applications requiring galvanic isolation. The model number encodes specific electrical parameters such as VA rating and secondary voltages.

Replacement Considerations

Direct substitutes include BV302D15015, BV302D15018, BV302D15020, BV302D15023, and BV302D15024, which share the same form factor but differ in secondary voltage ratings. Verify that the alternative secondary voltage matches the circuit design requirements before substitution.
