SMD type LAN pulse transformer ALT4532-001T (TDK-EPC)

TDK-EPC, a subsidiary of TDK Co., Ltd., developed the SMD-type LAN pulse transformer ALT4532-001T and started mass production in February. Compared with the previous products, this new product not only retains the same electrical characteristics (inductance: 200μH min., insertion loss: 1.5dB max.), but its product design can be applied to automation methods, achieving product quality improvement and stability. supply. This product not only increases the automatic winding function of the wire, but also realizes the automatic thermal compression combination with the connection of the electrode joint, and has fully and rationally designed the production process.

In particular, when it is used in a module, when the conventional product of the company is loaded, the substrate and the pulse transformer are first manually wired. Then, in order to maintain its stability, it is necessary to use a resin to fix the substrate and the parts. The SMD type new product can be used to complete the substrate loading by using the reflow method at one time, thereby simplifying the production process.

In addition, this product takes full advantage of SMD and, in combination with a common mode filter (used to remove differential transmission noise), achieves a further reduction in mounting area compared to previous products, which can satisfy customers. demand.

This product is used to transmit high-speed LAN (such as 100BASE-TX) differential transmission pulse signals, mainly used in digital home appliances.

Main applications: digital home appliances and more.

Main features: SMD products compatible with automatic coiling method to achieve customer's demand for product shape; Corresponding to automatic loading, reflow soldering, halogen-free substrates.
