Overview
The BV030-7335.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting. It features a primary voltage rating of 115V with parallel winding configuration. The secondary side offers versatile output options, providing 9V in parallel or 18V in series configurations. Maximum current outputs are rated at 256mA for the parallel secondary connection and 128mA for the series secondary connection. The unit has a power rating of 2.3VA and complies with RoHS standards.
Feature Summary
- Laminated core construction for efficient magnetic coupling
- Through-hole termination style for PCB integration
- Dual secondary voltage configuration supporting parallel and series connections
Applications
- General purpose AC to DC power supply circuits
- Industrial control system power isolation
- Consumer electronics internal power conversion
Procurement Notes
Verify the specific secondary winding requirement (parallel vs. series) against the target circuit design before procurement. Confirm that the 115V primary input aligns with the available line voltage in the application environment. Ensure through-hole footprint compatibility with the printed circuit board layout. Check for RoHS compliance documentation if environmental regulations apply to the final product assembly.
Selection Notes
Select this component when a 2.3VA isolation transformer is required for low-power applications. The dual secondary option allows flexibility for different voltage rails without changing the primary side. Consider thermal management capabilities relative to the 256mA or 128mA load requirements. Evaluate mechanical stability needs for through-hole mounting versus surface-mount alternatives.
Part Context
This part belongs to the Pulse Electronics power transformer family, specifically utilizing laminated core technology. It serves as an isolation component within power conversion stages. The model designation indicates specific electrical characteristics distinct from other variants in the series, such as different voltage ratings or core materials found in related products.
Replacement Considerations
Cross-reference with BV030-7305.0 for similar laminated core transformers, noting differences in primary voltage (230V vs 115V) and secondary specifications. Verify pinout compatibility and physical dimensions before substituting to ensure mechanical fit on the existing PCB.
FAQ
