ETH1-460L Description

Short technical summary and product information.

The Coilcraft ETH1-460L is a pulse transformer engineered to meet IEEE 802.3at-2009 and IEEE 802.3.bt Type 4 standards for Power over Ethernet (PoE+) and PoE++ applications. This component is designed for 4-pair cabling plants and supports 60/120 Watts, exceeding Gbit Ethernet return loss requirements.

 

Key electrical specifications include a minimum open-circuit inductance of 350 µH at 35 mA offset current and 25°C ambient temperature. It can handle a minimum DC offset of 22.5 mA at 85°C. The transformer provides 1500 Vrms winding-to-winding isolation. It operates within an ambient temperature range of -40°C to +85°C with a 1 A current.

 

This single-component solution can replace two ETH1-230 parts, optimizing board space. The core material is ferrite, and terminations are RoHS compliant tin-silver-copper over tin over nickel over phos bronze. The component has a weight of 3.6 g.

 

Packaging is provided on a 13-inch machine-ready reel (Code D), containing 250 parts per reel. The tape is EIA-481 embossed plastic tape, 32 mm wide and 0.5 mm thick, with 24 mm pocket spacing and 10.6 mm pocket depth. Resistance to soldering heat allows for a maximum of three 40-second reflows at +260°C, with parts cooled between cycles. The Moisture Sensitivity Level (MSL) is 1, indicating unlimited floor life under specified humidity conditions.
