Overview
The TOEP13-0155S1 is a Power over Ethernet (PoE) pulse transformer manufactured by Mentech Technology USA Inc. It features an inductance of 70µH and supports a power rating of 12W. The component utilizes a turn ratio of 1:0.32:0.84 and is designed for surface mount technology (SMT) applications. Its physical dimensions are 13.5mm x 15.5mm x 12.7mm. The device operates within a temperature range of -40°C to 125°C and complies with IEC60950 standards.
Feature Summary
- Designed specifically for Power over Ethernet (PoE) signal transmission and power delivery integration.
- Constructed for surface mount technology (SMT) to facilitate automated PCB assembly processes.
- Compliant with IEC60950 safety standards and RoHS environmental regulations.
Applications
- Power over Ethernet network interface cards
- Ethernet switch port circuits
- PoE injector modules
Procurement Notes
Verify the specific manufacturing date code and lot number upon receipt to ensure compliance with RoHS directives and IEC60950 standards. Confirm that the SMT footprint matches the design specifications of 13.5mm x 15.5mm x 12.7mm. Ensure storage conditions maintain integrity given the operating temperature range of -40°C to 125°C. Cross-reference the turn ratio of 1:0.32:0.84 with circuit requirements before final integration.
Selection Notes
Select this component when a PoE solution requires a 70µH inductance and 12W power handling capability. The SMT package size of 13.5x15.5x12.7mm must fit the available board space. Consider the wide operating temperature range of -40°C to 125°C for industrial or outdoor environments. Verify compatibility with IEC60950 standards if used in IT equipment contexts.
Part Context
This part belongs to the EFD series of PoE transformers from Mentech, focusing on integrated power and data transmission. The TOEP13-0155S1 variant specifically addresses high-power PoE applications requiring robust magnetic isolation. It serves as a critical interface component between Ethernet PHY controllers and the physical cabling infrastructure.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 70µH inductance, 1:0.32:0.84 turn ratio, and 13.5x15.5x12.7mm SMT footprint exactly.
