BV301S09020

Overview

The BV301S09020 is a 2VA laminated core power transformer from Zettler Magnetics, designed for through-hole mounting. It features a 115V primary winding and a single 9V secondary output capable of delivering up to 222mA. The device provides 2800Vrms isolation voltage between windings. Physical dimensions are 32.80mm in length and 27.80mm in width, with a maximum seated height of 27.40mm. The unit is fully encapsulated under vacuum pressure.

Feature Summary

• Fully encapsulated construction under vacuum pressure for enhanced efficiency and compactness
• Laminated core design providing stable electrical performance
• Through-hole termination style utilizing PC pins for secure board integration

Applications

• Linear power supply circuits requiring isolated AC voltage transformation
• General electronic equipment needing low-voltage AC power distribution
• Control systems utilizing standard laminated transformer architectures

Procurement Notes

Verify the specific ordering suffix against official Zettler Magnetics documentation to ensure correct pinout and insulation class compliance. Confirm that the 115V primary rating matches the target input voltage environment. Cross-reference the 222mA secondary current limit with load requirements to prevent thermal overload during operation.

Selection Notes

Select this component when a 2VA capacity is sufficient for the application's power budget. Ensure the PCB layout accommodates the 32.80mm x 27.80mm footprint and 27.40mm height clearance. Validate that the 2800Vrms isolation rating meets safety standards for the intended electrical separation requirements.
