Overview
The BV302D12024 is a 2.4VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting. It features a 230V primary input and a single 12V secondary output capable of delivering 100mA. The unit utilizes an EI30 laminated core with a case dimension of 32.8x27.8mm and a height of 27.4mm. Rated for 50/60Hz operation, it provides electrical isolation suitable for standard AC-DC conversion applications requiring compact, epoxy-sealed construction.
Feature Summary
- Encapsulated epoxy construction for environmental protection
- Through-hole mounting configuration for PCB integration
- EI30 laminated core design for efficient magnetic coupling
Applications
- General purpose AC-DC power supply units
- Control circuit isolation in industrial equipment
- Low-power consumer electronics adapters
Procurement Notes
Verify the specific suffix 'D' against the manufacturer's current datasheet to confirm the 100mA secondary rating, as variations exist within the BV series. Ensure the 230V primary voltage aligns with local grid standards. Confirm that the through-hole footprint matches the target PCB layout dimensions of 32.8x27.8mm before finalizing procurement orders.
Selection Notes
Select this component when a compact, encapsulated transformer is required for 230V mains input applications. The 2.4VA rating suits low-current loads, while the 12V output provides a common intermediate voltage level. Consider the physical height constraint of 27.4mm for enclosure design. This model offers a balance of cost-effectiveness and reliability for non-critical power stages.
Part Context
This part belongs to the BV Series of encapsulated power transformers by Zettler Magnetics. The series typically includes variants with different secondary voltages and current ratings, such as the BV302S12024 which shares similar physical dimensions but may differ in secondary specifications. The BV series is characterized by its use of EI laminations and epoxy potting for durability.
Replacement Considerations
Direct substitutes must match the 2.4VA rating, 230V primary, 12V secondary, and 100mA current capacity. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers' EI30-sized encapsulated transformers if Zettler availability is limited.
