Overview
The BV302S09018 is a 1.8 VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting on PCBs. It features a 230V AC primary input and a single 9V AC secondary output capable of delivering 200mA. The unit utilizes an EI30 laminated core with a height of 12.5mm and measures 32.8 x 27.8 mm in case dimensions. It operates at 50/60 Hz with a temperature class of Ta 40/B and provides 4.2kV dielectric strength.
Feature Summary
- Encapsulated construction for environmental protection
- Through-hole mounting for PCB integration
- EI30 laminated core design
Applications
- General purpose AC power supply circuits
- Industrial control panel power distribution
- Consumer electronics internal power conversion
Procurement Notes
Verify the specific datasheet version to confirm insulation class and regulatory approvals such as UL or CE before finalizing procurement. Ensure the 230V primary rating matches the local mains voltage standards. Confirm that the 1.8 VA power rating adequately supports the connected load requirements without exceeding thermal limits during continuous operation.
Selection Notes
Select this component when a compact, low-power isolation solution is required for 230V AC systems. The 1.8 VA rating suits light loads, while the encapsulated format offers durability. Consider the physical footprint of 32.8 x 27.8 mm for board layout constraints. Verify that the 9V secondary output aligns with downstream circuit voltage requirements.
Part Context
This transformer belongs to the BV Series of encapsulated power transformers by Zettler Magnetics. The series typically employs EI laminated cores and offers various power ratings and voltage configurations. The BV302S09018 specifically represents the 1.8 VA variant within the EI30_18 sub-series, providing standardized dimensions for consistent mechanical integration.
Replacement Considerations
Cross-reference part numbers such as BV302S09018-ND from distributor catalogs for equivalent sourcing. Verify that any substitute maintains the 1.8 VA rating, 230V primary, and 9V secondary specifications. Ensure mechanical compatibility regarding the EI30 core size and through-hole pin configuration.
