Overview
The BV202D12003A is a laminated power transformer from Zettler Magnetics, designed for through-hole mounting. It features a single primary winding rated for 230V input and dual secondary windings providing a 12V output at a maximum current of 14.6mA. The component has a power rating of 0.35VA and utilizes an EE20 core configuration. Physical dimensions are 23.0mm x 24.0mm with a case height of 16.0mm.
Feature Summary
- Through-hole construction with PC pin termination
- Dual secondary winding configuration
- Laminated core design
Applications
- Low-power electronic circuits requiring isolated AC-DC conversion
- Control systems utilizing 12V secondary outputs
- Industrial equipment with 230V primary supply requirements
Procurement Notes
Verify the specific datasheet for thermal derating curves and insulation class ratings before integration. Confirm that the 230V primary voltage aligns with your local mains frequency specifications. Ensure PCB pad layouts accommodate the specified through-hole pin spacing and physical envelope dimensions to prevent mechanical interference during assembly.
Selection Notes
Select this model when a compact, low-power transformer is needed for 230V to 12V isolation. The dual secondary option allows for flexible circuit design compared to single-output variants. Consider the EE20 core size constraints and ensure the 0.35VA rating meets the total load demand of the target application without exceeding thermal limits.
Part Context
This component belongs to the BV202 series of encapsulated power transformers manufactured by Zettler Magnetics. The series typically includes various voltage configurations sharing similar form factors. These units are engineered for general-purpose isolation in consumer and industrial electronics where space efficiency and reliable magnetic coupling are required.
Replacement Considerations
Direct substitutes include other BV202 series variants such as BV202D06003A or BV202D09003A if different secondary voltages are acceptable. Verify that any replacement maintains the same EE20 core size and through-hole pinout compatibility.
