Overview
The BV301D09012 is a 1.2VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting. It features an EI30 laminated core with a primary input of 115VAC and dual secondary outputs of 9VAC at 67mA each. The unit measures 32.8x27.8mm with a maximum height of 22.3mm. This component provides reliable isolation and voltage transformation for low-power applications requiring robust construction.
Feature Summary
- Encapsulated construction for environmental protection
- Dual secondary windings for split supply requirements
- Through-hole mounting configuration
- EI30 laminated core design
Applications
- LED lighting systems
- Electric metering devices
- Motor controls
- Thermostats
Procurement Notes
Verify the specific datasheet version to confirm insulation class and regulatory approvals such as UL or CE before integration. Ensure the PCB footprint matches the 32.8x27.8mm case dimensions and that the through-hole pins align with the board layout. Confirm that the 115V primary rating matches the local mains frequency and voltage standards.
Selection Notes
Select this model when a compact, encapsulated transformer is required for low-power AC-DC conversion stages. The dual 9V secondaries are suitable for circuits needing isolated bipolar supplies or redundant paths. Consider the 1.2VA power limit and ensure the load current does not exceed 67mA per secondary winding to maintain performance.
Part Context
This component belongs to the BV Series of encapsulated power transformers by Zettler Magnetics. The series is characterized by compact designs suitable for space-constrained applications. These transformers are engineered for off-line and SMPS power sources, meeting stringent design requirements for reliability in consumer and industrial electronics.
Replacement Considerations
The BV301D10012 is a documented alternative within the same series, offering identical physical dimensions and VA rating but with 10VAC secondaries instead of 9VAC. Verify that the circuit design can accommodate the voltage difference. No other direct substitutes are confirmed in public documentation.
