B82806D0060A033

Overview

The B82806D0060A033 is a Power over Ethernet (PoE) transformer manufactured by EPCOS, now part of TDK Electronics. This component is designed for use in SMD push-pull converter applications and features an EFD20 core configuration. It provides galvanic isolation with a rated voltage of 500VAC between primary and secondary windings. The device supports switching frequencies up to 250kHz and operates within a temperature range of -25°C to 125°C. Its compact surface-mount package measures 8.00mm x 9.60mm with a maximum height of 5.70mm, facilitating integration into space-constrained electronic designs.

Feature Summary

• Integrated galvanic isolation for PoE signal transmission
• Optimized for SMD push-pull converter topologies
• High thermal stability supporting extended industrial temperatures

Applications

• Power over Ethernet network interface cards
• SMD push-pull DC/DC converters
• Industrial communication modules requiring isolated power

Procurement Notes

Verify the specific manufacturer designation, as EPCOS components are now branded under TDK Electronics. Confirm that the ordering suffix matches the required pinout and insulation class for your design. Ensure the component meets RoHS compliance standards if mandated by your project specifications. Cross-reference the datasheet parameters against your system's electrical requirements before finalizing procurement.

Selection Notes

Select this component when designing PoE interfaces requiring integrated magnetics with high isolation ratings. The EFD20 core size offers a balance between performance and footprint for surface-mount assembly. Consider the 250kHz frequency capability and wide operating temperature range for robustness in demanding environments. Ensure compatibility with push-pull converter architectures during the schematic phase.

Part Context

This transformer belongs to the B82806 series, which includes various PoE transformer variants from EPCOS/TDK. These components are engineered to meet IEEE 802.3 standards for data transmission over Ethernet cables while providing necessary isolation. The series is widely used in modern networking equipment to simplify board layout by combining magnetic coupling and isolation in a single package.

Replacement Considerations

Consult official TDK Electronics documentation for direct cross-references. Verify pin-to-pin compatibility and electrical equivalence with alternative PoE transformers from the same manufacturer family.
