LF8275 Description

Short technical summary and product information.

The Delta Electronics LF8275 is a 10/100Base-Tx Transformer, a crucial component for networking applications. This transformer is engineered to meet specific electrical performance criteria, including an insertion loss of -1.0 dB across a frequency range of 1-100 MHz and a minimum return loss of -18 dB from 1-30 MHz.

Further electrical specifications include a common-to-common crosstalk of -65 dB (1-60 MHz) and differential-to-common crosstalk of -45 dB (1-60 MHz). The device also features a mode rejection ratio of -40 dB (1-60 MHz) and a turns ratio of 1:1 / 1:1. It is designed for reliable operation with a Hi-Pot test at 1500Vrms for 60 seconds and an OCL of 350uH (Min) at 8mA DC bias.

Mechanically, the LF8275 has dimensions of 8.89 mm in length, 10.67 mm in width, and 6.86 mm in height, with a typical pin pitch of 1.27 mm and lead spacing of 0.64 mm. These specifications make it suitable for integration into various electronic designs requiring robust network signal transmission.
