Overview
The BV301S12010 is a sealed power transformer from Zettler Magnetics' EI30-10.5 series, designed for low-power applications requiring galvanic isolation. It features a 1VA rating with a 115V primary and 12V secondary output capable of 83mA. The unit utilizes through-hole PC pin termination and offers a 4200Vrms isolation voltage. Constructed with a bobbin core type, the component measures 16.5 mm in length and supports operating temperatures up to 70°C or higher, ensuring reliability in compact electronic designs.
Feature Summary
- Provides galvanic isolation between primary and secondary circuits
- Encapsulated construction for environmental protection
- Through-hole mounting for secure PCB integration
Applications
- Thermostats
- Lighting controls
- Low-power electronic devices requiring isolation
Procurement Notes
Verify the specific datasheet version for the BV301S12010 to confirm insulation class and temperature ratings. Ensure the procurement documentation matches the manufacturer's official specifications for the EI30-10.5 series. Cross-reference terminal configurations and isolation voltages against system requirements before finalizing orders.
Selection Notes
Select this component when a 1VA isolated power supply is needed for AC mains input. The 12V secondary output suits low-current control circuits. Verify that the physical dimensions fit the enclosure and that through-hole assembly processes are available for the manufacturing line.
Part Context
This transformer belongs to Zettler Magnetics' BV series, which covers output loads from 0.6 to 10VA. The EI30-10.5 model designation indicates the core geometry and size class within the encapsulated power transformer family, targeting compact industrial and consumer electronics.
Replacement Considerations
Check for direct substitutes within the BV301 series with different secondary voltages if the 12V output does not match the circuit design. Ensure any replacement maintains the same 1VA rating and 4200Vrms isolation capability.
