BV042-5055.0

Overview

The BV042-5055.0 is a laminated core power transformer manufactured by Pulse Electronics Corporation, designed for through-hole mounting. It features an 115V primary voltage and a single 12V secondary output. The unit provides a maximum output current of 417mA with a total power rating of 5VA. Constructed with a laminated core, it supports standard AC line frequencies. The component is RoHS compliant and intended for general power supply applications requiring isolated voltage conversion.

Feature Summary

• Laminated core construction for efficient magnetic flux transfer
• Through-hole mounting style for secure PCB integration
• Single secondary winding providing isolated 12V output
• RoHS compliant manufacturing standards

Applications

• General purpose AC to DC power supplies
• Low voltage equipment power conditioning
• Consumer electronics internal power stages

Procurement Notes

Verify the specific datasheet version for electrical tolerances and thermal characteristics before integration. Confirm that the through-hole footprint matches the target PCB layout dimensions. Ensure the 115V primary input aligns with the local mains voltage requirements. Check RoHS documentation status for regulatory compliance in the destination market. Validate insulation class ratings against safety standards applicable to the end product.

Selection Notes

Select this transformer when a 5VA isolation barrier is required between primary and secondary circuits. The 115V primary specification suits regions utilizing standard North American or similar AC line voltages. Consider the physical size constraints as through-hole components occupy more board area than surface-mount alternatives. Evaluate thermal dissipation needs given the 417mA continuous current capability. Ensure the application does not require multiple secondary outputs or higher power density.

Part Context

This component belongs to the Power Transformers category within Pulse Electronics' portfolio. It serves as a fundamental isolation device for converting standard AC line voltage to lower DC-compatible levels. The laminated core design distinguishes it from high-frequency switching transformers, targeting linear power supply architectures. It complements rectifier and filtering components to form complete low-power AC-DC conversion modules.
