BV048-5055.0

Overview

The BV048-5055.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting on printed circuit boards. It features an EI48/16.8 split bobbin construction with a rated power capacity of 10VA. The device operates with an 115V primary winding and provides a single 12V secondary output capable of delivering up to 834mA. This component is engineered for standard AC line voltage applications requiring isolated DC power conversion.

Feature Summary

• Utilizes a laminated iron core structure for efficient magnetic flux conduction
• Incorporates a split bobbin design to facilitate automated assembly processes
• Provides galvanic isolation between primary and secondary circuits
• Supports direct through-hole integration into PCB layouts

Applications

• General purpose AC to DC power supply units
• Industrial control system power modules
• Consumer electronics internal power adapters
• Low-voltage equipment isolation stages

Procurement Notes

Verify the specific datasheet version prior to ordering, as manufacturing revisions may alter physical dimensions or electrical tolerances. Confirm that the 115V primary rating aligns with the target input voltage infrastructure. Ensure the through-hole footprint matches the designated PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this transformer when a 10VA isolation barrier is required between mains and low-voltage sections. The 12V secondary output suits logic circuits and small motors. Consider the thermal dissipation characteristics of the laminated core in enclosed designs. Evaluate the physical size of the EI48 core against available board space. Verify that the 834mA current limit meets the peak load requirements of the downstream circuitry.

Part Context

This component belongs to the Pulse Electronics power transformer family, specifically categorized under board-mount laminated cores. It serves as a fundamental isolation element in linear power supplies. The model designation indicates specific core geometry and winding configuration. It replaces older generic transformers with standardized pinouts for easier integration into modern electronic assemblies.

Replacement Considerations

Consult official distributor archives for confirmed obsolete part substitutes. Cross-reference equivalent models from other manufacturers only if they match the 10VA rating, 115V primary, and 12V secondary specifications exactly. Verify mechanical compatibility before swapping components.
