BV201D10005

Overview

The BV201D10005 is a 0.5VA encapsulated power transformer from the EE20_05 series by Zettler Magnetics. It features a single 115V primary winding and dual 10V secondary windings, each rated for 50mA. The unit utilizes an EE20 core with a lamination height of 10.5mm. Physical dimensions are 23.0 x 24.0mm with a maximum height of 19.5mm. It employs through-hole mounting and weighs approximately 40g.

Feature Summary

• Fully encapsulated under vacuum pressure for enhanced efficiency and compactness
• Dual secondary windings providing isolated output channels
• Through-hole construction for standard PCB integration

Applications

• Linear power supply circuits
• Low-power electronic equipment
• Control system transformers

Procurement Notes

Verify that the required input voltage matches the specified 115V primary rating to ensure proper operation. Confirm that the load current does not exceed the 50mA limit per secondary winding to prevent thermal overload. Check physical clearance requirements against the 23.0 x 24.0mm footprint and 19.5mm height. Ensure the application environment supports the operating temperature range indicated in the official datasheet.

Selection Notes

Select this component when a low-power, encapsulated solution is required for linear power architectures. The dual secondary design allows for separate voltage rails without additional isolation components. Consider the through-hole form factor if surface-mount alternatives are unsuitable. Evaluate the 0.5VA capacity against total system power consumption to ensure adequate headroom for transient loads.

Part Context

This transformer belongs to the BV series of laminated power transformers manufactured by Zettler Magnetics. The series is characterized by vacuum-pressure encapsulation techniques designed to improve thermal performance and reduce size compared to traditional open-frame designs. The EE20 core geometry provides a standardized footprint for various VA ratings within the product line.

Replacement Considerations

Consult the manufacturer's official cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains the same electrical specifications, including 115V primary input and dual 10V/50mA secondaries. Verify mechanical compatibility regarding pin spacing and overall dimensions before implementation.
