It seems that almost every industry has transitioned to Ethernet for their networking needs because of its increased bandwidth capabilities that can support real-time data sharing needs. Ethernet-based transformers are used in these applications to meet the isolation and signal conditioning requirements for connected communication. The high reliability mandated in communication systems can be threatened by coupling signals from devices that work with different power specifications. If there is a fault operation in one device, it can potentially spread to other connected devices compromising the overall performance and reliability of the network.
Adding to the challenge is that IT equipment manufacturability trends call for component suppliers to meet miniaturization, higher manufacturing yield rates, and strict product quality metrics. Manufacturing traditional LAN transformers typically utilizes a great deal of manual labor in the winding process, which can result in higher production costs and inconsistent quality. That’s why Bourns is continually making technology advancements that make smaller form factors with consistent feature sets possible. The innovations we’ve achieved also help us deliver transformers that offer high-quality signal conditioning performance in a device designed for fully-automated production.
In a new white paper, Bourns introduces a new type of Chip-LAN transformer that has been optimized for Ethernet-based IT equipment. Reading the white paper, you will learn about the Chip-LAN transformer’s construction advantages along with the benefits from its toroid core magnetic path design. Unlike traditional LAN magnetics built with multiple toroidal core transformers and common mode chokes in a single module, the Chip-LAN transformer is a discrete, center-tapped component wound on a drum core and capped with a ferrite plate to emulate the result of the close magnetic path of a toroid core. A common mode chip inductor pairs with a Chip-LAN transformer to provide EMI suppression.
The paper also presents how the Chip-LAN design overcomes the lower product stability and extensive manufacturing manpower drawbacks experienced with traditional network transformers. Discover how the structure of this transformer helps IT equipment companies meet their SMT process and product quality and consistency goals.
