BV201S18005

Overview

The BV201S18005 is a 0.5VA encapsulated power transformer from the Zettler Magnetics BV Series, designed for through-hole mounting. It features a single primary winding rated for 115V input and a single secondary winding providing 18V at full load with a maximum current of 27.8mA. The component utilizes an EE20 core configuration and measures 24.00mm in length by 23.00mm in width, with a maximum height of 19.5mm. This unit is RoHS compliant and intended for general-purpose voltage transformation in compact electronic assemblies.

Feature Summary

• Encapsulated construction for mechanical protection and environmental resistance
• Single primary to single secondary winding configuration for standard isolation
• Through-hole PC pin termination for reliable board integration
• Compact EE20 core design optimized for space-constrained applications

Applications

• Low-power AC-DC power supply front ends
• Control circuit isolation stages
• Signal conditioning interface transformers
• Consumer electronics internal power distribution

Procurement Notes

Verify the specific datasheet version for the BV201S18005 to confirm insulation class and thermal ratings prior to integration. Ensure that the PCB footprint matches the through-hole pin spacing dimensions provided in the official mechanical drawing. Confirm compliance requirements such as RoHS status align with project specifications before finalizing procurement orders.

Selection Notes

Select this model when a low-voltage, low-current isolated output is required from a 115V source. The 0.5VA rating limits suitability to small signal or control applications rather than high-power loads. Consider the physical dimensions and through-hole requirement against available board space and assembly capabilities compared to surface-mount alternatives.

Part Context

This component belongs to the BV Series of encapsulated power transformers manufactured by Zettler Magnetics. The series typically employs EE20 laminations and offers various voltage configurations tailored for industrial and consumer electronics. These transformers are characterized by their robust encapsulation and standardized through-hole form factors suitable for automated assembly processes.

Replacement Considerations

Direct substitutes include other 0.5VA, 115V-to-18V through-hole transformers from Zettler such as the BV202S18005 if higher current capacity is acceptable, or equivalent models from manufacturers like TDK-Lambda or Coilcraft that match the 24.0x23.0mm footprint and electrical specifications.
