Overview
The BV301S18020 is a 2VA encapsulated power transformer designed for through-hole mounting. It features dual primary windings rated for 115V and 230V inputs at 50/60Hz frequencies. The secondary winding provides an 18V output with a maximum current capacity of 111mA. This component utilizes PC pin termination for secure board integration.
Feature Summary
- Fully encapsulated under vacuum pressure to ensure compact size and operational efficiency
- Dual primary winding configuration supporting both 115V and 230V input voltages
- Through-hole installation method utilizing PC pin termination style
Applications
- Linear power supply circuits requiring isolated AC voltage transformation
- Electronic equipment needing 115V or 230V to 18V step-down conversion
- General-purpose industrial control systems utilizing laminated core transformers
Procurement Notes
Verify the specific part number against official Zettler Magnetics documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with existing PCB layouts regarding through-hole spacing and enclosure requirements before finalizing procurement decisions.
Selection Notes
Select this model when a 2VA isolation transformer is required for standard line voltages. The 18V secondary rating suits applications needing moderate voltage reduction. Verify that the 111mA current limit meets the downstream circuit demands without exceeding thermal constraints.
Part Context
This component belongs to the BV series of encapsulated power transformers from Zettler Magnetics. These units are characterized by their laminated core construction and vacuum-encapsulated design, which enhances reliability while maintaining a small form factor suitable for dense electronic assemblies.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalent part numbers. Cross-reference electrical specifications such as VA rating, primary/secondary voltages, and current limits to ensure functional compatibility during replacement scenarios.
