BV030-7198.0

Overview

The BV030-7198.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting on printed circuit boards. It features a single primary winding rated for 230V input and a single secondary winding providing 12V output at a maximum current of 42mA. The unit has a total power rating of 0.5VA. Its physical dimensions are specified as 32.50mm in length and 27.50mm in width. This component serves as an isolation transformer for low-power AC applications requiring step-down voltage conversion from standard mains levels to a lower DC-compatible AC level.

Feature Summary

• Laminated core construction for efficient magnetic flux coupling
• Through-hole termination style for robust PCB integration
• Single primary to single secondary winding configuration
• Compact rectangular form factor suitable for constrained spaces

Applications

• Low-power AC signal isolation
• Step-down voltage conversion for control circuits
• Power supply input stages for small electronic devices
• Isolation barriers in measurement equipment

Procurement Notes

Verify the specific manufacturing date code and lot number upon receipt to ensure compliance with project timelines. Confirm that the through-hole pin spacing matches the target PCB footprint exactly. Check for any mechanical damage to the laminated core or insulation during transit. Ensure the receiving facility has appropriate handling procedures for fragile transformer components. Validate that the component meets all required safety certifications for the intended market before final assembly.

Selection Notes

Select this transformer when a 230V to 12V isolation step-down is required for low-current applications up to 42mA. The 0.5VA power rating limits its use to small loads, making it unsuitable for high-power drives. Consider the through-hole mounting requirement against available board space and automation capabilities. Evaluate the physical dimensions of 32.50mm x 27.50mm against the enclosure constraints. Ensure the operating environment does not exceed the thermal limits of the laminated core insulation.

Part Context

This component belongs to the Power Transformers category within Pulse Electronics' portfolio. It is distinct from surface-mount RF inductors or common mode chokes offered by the same manufacturer. The BV series typically denotes laminated core transformers designed for general-purpose power isolation. It contrasts with switch-mode power supplies by providing direct magnetic coupling without active regulation.

Replacement Considerations

Public records indicate this part number is obsolete. Engineers must identify equivalent transformers with matching 0.5VA rating, 230V primary, 12V secondary, and compatible through-hole pin pitch. Verify that substitute models maintain identical electrical isolation standards and physical envelope dimensions to ensure fitment.
