BV302S09015

Overview

The Zettler Magnetics BV302S09015 is a sealed power transformer designed for through-hole mounting. It features a 230V primary input operating at 50/60Hz and provides a single 9V secondary output capable of delivering 167mA. The unit has a rated power of 1.5VA with an EI30 core size and a turns ratio of 26:1. Physical dimensions are 32.8x27.8mm with a height of 24.5mm. It offers a dielectric strength of 4.2kV, insulation resistance of 100MOhm, and operates within a temperature class of Ta 70/B.

Feature Summary

• Sealed encapsulated construction for environmental protection
• EI30 laminated core design for efficient magnetic coupling
• High dielectric strength ensuring electrical isolation safety

Applications

• General electronic equipment power supplies
• Control circuit voltage stepping
• Industrial instrumentation power modules

Procurement Notes

Verify the specific ordering suffix matches the required secondary voltage and current rating. Confirm that the through-hole package style aligns with the target PCB layout. Ensure the thermal class meets the operational environment requirements. Check datasheet specifications for dielectric strength limits to guarantee system safety compliance.

Selection Notes

Select this component when a compact, sealed transformer is needed for 230V AC to low voltage DC conversion. The 1.5VA rating suits low-power applications requiring reliable isolation. Consider the physical footprint constraints as the case dimensions are fixed. Verify that the 167mA output current meets the load requirements without exceeding thermal limits.

Part Context

This part belongs to the BV Series of encapsulated power transformers from Zettler Magnetics. The series utilizes EI30 laminations and offers various voltage configurations. The BV302S09015 specifically denotes the 9V secondary variant within this family, sharing common mechanical and insulation characteristics with other models in the line.

Replacement Considerations

Direct substitutes must match the 1.5VA rating, 230V primary, and 9V secondary output. Compatible alternatives include other BV302S variants with identical pinouts and dimensions. Verify that any replacement maintains the same dielectric strength and thermal class specifications.
