- Widespread LAN Transformer

由美國在1980年代所開發的乙太網路，隨著資訊時代的來臨，已經被網路系統普遍的使用。
依照應用的需求不同，乙太網路的傳送速度一般分為10/100Mbps與1/10Gbps兩種，是為LAN的主流，因為已經被廣泛的使用，做為網路連接各電子IT產品的LAN端子，成為了大部分電子IT產品的必要配備。
尤其為了對應輕薄短小的趨勢，部分有高度限制的產品必須把LAN的端子分開為RJ45接頭與LAN Transformer以實現薄型化的訴求。The Ethernet was developed by US in 1980s. Depends on the widespread Information Technology (IT), the Ethernet has been well-spread in internet system.
According to the different applications, the major 2 transmission speeds of Ethernet are 10/100Mbps and 1/10Gbps, that has been applied in most IT equipment over 20 years, so that the LAN interfaces have became standard features in recent years.
Especially to meet the trend of slim in IT equipment, some height limited equipment must divide LAN device into RJ45 connector and LAN transformer to approach the low-profile achievement.Trend of Ethernet
LAN Transformer Application
- Traditional LAN Transformer
-
傳統LAN Transformer結構，包含：
‧電木外殼與鍍錫接點
‧環型鐵芯
‧漆包線
‧環氧樹脂
由於為了避免磁漏所採用的環型鐵芯不利於自動化繞線，所以傳統的LAN Transformer都是採用人工繞線，也因此會有繞線特性不均衡，影響傳輸品質與交期長的缺點。
The structure of traditional LAN Transformer, including:
‧Plastic Case with Tin plated PIN
‧Toroidal Ferrite Cores
‧Enamelled Copper Wire
‧Epoxy
Although the toroidal ferrite core can prevent leakage flux, the toroid shape is hard to wind the wire automatically, so the traditional LAN transformer is manufactured manually. Therefore, the manual winding process cause the disadvantages of the unstabilities in transmission quality and long lead time.
