Push-Pull Converter Transformer

RS-485 (EIA/TIA-485 Standard)is a balanced differential bus standard for serial communication, published by the Electronic Industries Alliance in 1983. The RS-485 bus features long-distance transmission, multi-node networking, and strong common-mode rejec

From the PHY and LAN transformer to common-mode chokes and port protection, VOOHU shows how to build TSN determinism on a solid physical-layer foundation, with a selection table for 1G / 2.5G / EtherCAT / PoE ports.

The network port RJ45 connector is randomly selected as a mechanical part that "can be plugged into a network cable". As a result, the radiation emission exceeds the standard, ESD kills it, the shielded network cable is even worse when plugged in, and the board is thin but cannot be installed in the casing. VOOHU thoroughly explains the selection from three main lines: the choice between integrated magnetic RJ45 and discrete RJ45 + external network transformer, whether the shielding shell is grounded at the bottom (Bob-Smith and chassis ground), tab orientation/sunken plate/low back/

Nowadays, more and more devices have local area network (LAN) connectivity. To facilitate communication, the simplest solution is to power the devices via a LAN cable (Power over Ethernet), thus eliminating the need for a separate power supply.PoE Transfo

VOOHU Electronics officially launched two new coupler male and female connectors, WHKNZ63YSCAT6a and WHKNZ63CAT6a180, which focus on 10 Gigabit (CAT6A) transmission rate. They adopt industrial-grade metal shell design and support PoE power supply. They are targeted at connection scenarios with high speed and reliability requirements such as industrial Ethernet, outdoor security and PoE front-end. The metal male connector WHKNZ01000FS is an existing product of VOOHU and can be used with two new products. For product selection and technical support, please visit VOOHU's official platform WW

In Ethernet hardware circuit design, the LAN Transformer is a core component that ensures signal transmission and provides electrical isolation. The isolation transformer and common‑mode choke (CMC), as the two key supporting components of the Ethernet tr
