SM51625L Description

Short technical summary and product information.

The Bourns SM51625L is a specialized LAN transformer engineered to meet the demands of modern networking applications, including 10/100/1000 Base-T Ethernet and Power over Ethernet Plus (PoE++).

 

This transformer features a 1CT:1CT turns ratio and is designed for efficient power delivery, supporting PoE up to 1.2 ADC per center tap. Key electrical specifications include an Open Circuit Inductance (OCL) of 80 μH minimum at 100 kHz, a maximum leakage inductance of 0.5 μH, and a maximum DCR of 1.4 ohms for the transmit/receive (TD) windings.

 

It also provides excellent signal integrity with low insertion loss and high common mode rejection across a wide frequency range. The operating temperature range is from -40°C to +85°C, making it suitable for various environmental conditions. The transformer is supplied in tape and reel packaging, with 350 pieces per reel.

 

Applications for the SM51625L include general LAN and Ethernet connectivity, particularly where Power over Ethernet is utilized, ensuring reliable data and power transmission.
