TRANSFORMER EDSO-G16

Category: Electronics, Transformers, Wrth Elektronik Group

Overview

The TRANSFORMER EDSO-G16 datasheet provides detailed information on a transformer designed to handle 350mA DC and to meet the 802.3af standard. The component features a RoHS compliant and lead-free design, signified by its LF1 designation which relates to its solder material composition of 96% tin (Sn) and 4% silver (Ag).

Physical Characteristics

The datasheet describes the physical layout of the transformer, including terminal dimensions and placement. A key feature is the recess which orients Terminal #1, and the importance of coplanarity is emphasized – all 16 terminals must be within 0.004 inches of the surface after tinning. The recommended land layout for the RX terminal is provided, along with various measurements for terminal pads, which are to be determined by the customer.

Electrical Specifications

Dielectric Rating: The transformer has a dielectric rating of 1500Vrms for one minute, tested by applying 180Vrms for 1 second between specified terminal groups.
Inductance: It offers a minimum inductance of 350uH at 100kHz, 100mV AC, and 8mA DC on specific terminal pairs.
Turns Ratio: Two turns ratios are provided, both at 1:1, for different terminal pairings.
Insertion Loss: The component is rated for a maximum insertion loss of 1.2dB across a frequency range of 1MHz to 100MHz.
Return Loss: It specifies minimum return losses at varying dB levels for frequencies ranging from 1MHz to 80MHz.
Crosstalk: A minimum crosstalk of 35dB between 1MHz to 100MHz is stated.
DCMR: Differential to common mode rejection is also at a 35dB minimum within the same megahertz range.
Operating Temperature Range: The operating temperature range is specified from 0°C to +70°C.
