The document describes a series of Fast Ethernet transformers with different specifications and parameters. These transformers have different turns ratios, insertion loss, return loss, and common mode rejection ratios.
This datasheet provides the electrical performance data for Abracon's LAN coupling transformers, covering both Fast Ethernet and Gigabit Ethernet series. It lists part numbers, turns ratios, frequency ranges, insertion loss, crosstalk, and package dimensions.
The document also includes test conditions, notes on configuration (through‑hole vs. surface‑mount, center‑tapped windings), and environmental limits such as operating temperature and dielectric withstand voltage.
| Open‑Circuit Loss (OCL) | 100 mV·A·s @ 100 kHz with 8 mA DC |
|---|---|
| Dielectric Withstand Voltage (DWV) | 1 500 V·A·s for 1 minute (minimum) |
| Operating Temperature Range | -40 °C to 85 °C |
| Bias Current | 8 mA (minimum) steady‑state DC |
The open‑circuit loss is specified as 100 mV·A·s at 100 kHz with an 8 mA DC bias.
Test conditions include an OCL of 100 mV·A·s @ 100 kHz with 8 mA DC, bias current of 8 mA minimum, and a dielectric withstand voltage of 1 500 V·A·s for 1 minute.
They are rated for operation from –40 °C to +85 °C and must meet a dielectric withstand voltage of 1 500 V·A·s for at least one minute.
