BV048-5193.0

Overview

The BV048-5193.0 is a laminated core power transformer manufactured by Pulse Electronics Corporation, designed for through-hole mounting on printed circuit boards. It features an EI48/16.9 split bobbin construction with a 230V primary winding and a single 12V secondary output. The unit provides a rated power capacity of 10VA, supporting a maximum secondary current of 834mA. This component is RoHS compliant and intended for general-purpose AC voltage transformation in electronic assemblies requiring isolated power supply stages.

Feature Summary

• Laminated core construction utilizing EI48/16.9 geometry for efficient magnetic flux coupling
• Split bobbin design facilitating secure winding placement and structural stability
• Through-hole termination method ensuring robust mechanical attachment to PCB substrates

Applications

• General-purpose AC power supply units
• Electronic equipment requiring isolated low-voltage DC conversion
• Industrial control systems with standard mains input requirements

Procurement Notes

Verify the specific datasheet version provided by the manufacturer or authorized distributor to confirm insulation class and safety certifications relevant to your target market regulations. Ensure that the through-hole footprint matches your PCB layout constraints. Confirm RoHS compliance status if operating in regions with strict hazardous substance restrictions. Cross-reference the 10VA rating against your system's peak load requirements to prevent thermal overload during continuous operation.

Selection Notes

Select this component when a standard 230V to 12V isolation transformer is required for through-hole assembly processes. The 10VA rating suits applications with moderate power demands where compact surface-mount solutions are not feasible. Consider the physical dimensions of the EI48 core and the lead spacing to ensure compatibility with existing manufacturing equipment and enclosure space limitations without requiring custom tooling or layout modifications.

Part Context

This transformer belongs to Pulse Electronics' line of board-mount power transformers, specifically utilizing the EI48 core size which balances performance with cost-effectiveness for medium-power applications. The BV048 series designation indicates a standardized form factor widely used in legacy and modern designs alike. As a laminated core device, it offers reliable performance for fixed-frequency mains applications compared to high-frequency switch-mode alternatives.

Replacement Considerations

The ASL160112BO from S&B Tech is a documented substitute offering identical 10VA power, 230V primary, and 12V secondary specifications. Verify mechanical lead spacing and overall height clearance before substitution to ensure fit within the designated PCB area and housing constraints.
