BV202D12005

Overview

The BV202D12005 is a 0.5VA encapsulated power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a primary voltage rating of 230V and provides dual secondary outputs of 12.5V and 12V. The secondary current capacity is specified at 20.8mA. The component utilizes an EE20 laminated core with a case dimension of 23.0x24.0mm and a height of 19.5mm.

Feature Summary

• Encapsulated construction for environmental protection
• Dual secondary winding configuration
• Through-hole mounting style

Applications

• General purpose AC-DC power supply circuits
• Low power electronic equipment
• Control circuit isolation

Procurement Notes

Verify the specific datasheet revision and regulatory compliance certificates (such as UL or CQC) required for your target market before finalizing procurement. Ensure that the through-hole footprint dimensions match your PCB layout constraints. Confirm that the 0.5VA rating meets the thermal and electrical load requirements of the intended application to prevent overheating or performance degradation under full load conditions.

Selection Notes

Select this component when a compact, low-power isolation solution is needed for mains-connected devices. The dual secondary output allows for separate voltage rails without additional transformers. Consider the physical size constraints of the EE20 core design and ensure adequate clearance distances are maintained on the PCB for safety insulation requirements associated with primary-to-secondary isolation.

Part Context

This part belongs to the BV series of encapsulated power transformers from Zettler Magnetics. The series is characterized by small form factors suitable for space-constrained applications. The BV202D12005 specifically addresses low-voltage, low-current needs common in consumer electronics and industrial control panels where simple galvanic isolation is required.

Replacement Considerations

Direct substitutes must match the 0.5VA rating, 230V primary input, and dual secondary voltages. Verify mechanical compatibility including the EE20 core type and through-hole pin spacing. Cross-reference with other manufacturers' encapsulated transformers offering identical electrical specifications and safety certifications to ensure interchangeability.
