Overview
The BV301D18028 is a laminated power transformer from Zettler Magnetics, designed for through-hole mounting. It features an EI30 lamination size with a case dimension of 32.8mm x 27.8mm and a height of 29.8mm. The unit has a rated power of 2.8VA and operates at input frequencies of 50/60Hz. The primary winding accepts 115V AC input. The secondary configuration provides dual outputs of 18V each, supporting a maximum current of 70mA per secondary winding.
Feature Summary
- Encapsulated construction for environmental protection
- Through-hole termination style for PCB integration
- Dual secondary windings for split voltage requirements
Applications
- General purpose AC to DC power supply circuits
- Industrial control panel power distribution
- Consumer electronics internal power conversion
Procurement Notes
Verify the specific secondary voltage configuration and current rating against the application schematic before procurement. Confirm that the through-hole pin spacing matches the target printed circuit board layout. Ensure the operating frequency aligns with the 50/60Hz specification to maintain performance integrity. Check for any required safety certifications relevant to the end product's market.
Selection Notes
Select this component when a compact, encapsulated transformer is required for low-power applications. The 2.8VA rating suits devices with modest energy demands. Consider the physical dimensions of 32.8mm x 27.8mm for enclosure space constraints. The dual 18V output is suitable for circuits requiring symmetrical or isolated secondary rails.
Part Context
This model belongs to the BV series of encapsulated power transformers by Zettler Magnetics. The series utilizes EI30 laminations to provide efficient magnetic coupling in a small footprint. These transformers are engineered for reliability in standard industrial and commercial environments, offering a balance between size and power handling capacity.
Replacement Considerations
Direct substitutes must match the 2.8VA rating, 115V primary, and dual 18V secondary specifications. Verify that alternative components maintain the same through-hole pin configuration and overall envelope dimensions to ensure mechanical compatibility without redesigning the host circuit board.
FAQ
