Procurement Notes
Verify the specific part number suffix against official manufacturer documentation to confirm electrical ratings and physical dimensions. Confirm availability status as the product may be discontinued or subject to limited stock. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement orders.
Selection Notes
Select this component when a 5VA laminated core transformer is required for 230V primary input applications. Ensure the design accommodates the through-hole mounting style and the specified physical envelope dimensions. Verify that the 18V secondary output aligns with downstream circuit voltage requirements and current demands not exceeding 278mA.
Part Context
This power transformer belongs to the Pulse Electronics BV042 series, which focuses on general-purpose laminated core transformers. These components are typically utilized in switch-mode power supplies and linear power supply designs where reliable isolation and moderate power handling are necessary for various electronic equipment applications.
Replacement Considerations
Consult official distributor catalogs for cross-reference data. Verify equivalent specifications such as core type, voltage ratios, and current ratings before substituting with alternative manufacturers' parts to ensure functional compatibility.
