【Frequently Asked Questions】Placement of Common‑Mode Choke in Ethernet Transformers: Detailed Explanation for Non‑PoE and PoE Scenarios – VOOHU

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
VOOHU Electronics cordially invites you to attend the Munich Shanghai Electronics Show

As a beacon exhibition and important event in the electronics industry, electronica China has a 20-year history and has become a professional platform leading future electronic technology innovation and technology exchange. At this exhibition, Voohu will s
RJ45 Integrated Magnetics Connector: VOOHU SYT111B002HWA1D as a Replacement for Pulse JX0011D21NL

VOOHU SYT111B002HWA1D is a single-port 1×1, 10/100Base Tab-Down integrated-magnetics RJ45 (no LED, industrial -40 to +85°C). Its turns ratio, insertion/return loss, crosstalk and isolation correspond one-to-one with Pulse JX0011D21NL, making it a pin-to-pin replacement.
Detailed explanation of VOOHU: PoE switch (PSE side) multi-port network port design - multi-port integrated magnetic RJ45, network transformer bias and port crosstalk/heat dissipation pit avoidance

The PSE port of the PoE switch is not a simple copy and paste of the network port. This article dismantles the design points of the PSE side from five dimensions: network transformer DC bias, multi-port integrated magnetic RJ45 and discrete network transformers, inter-port crosstalk and Bob Smith termination, three-level surge protection and thermal design, and provides a VOOHU on-rack material number selection table.
VOOHU Field Guide: Selecting 10/100BASE-TX Ethernet LAN Transformers and ESD / Surge Protection

10/100BASE-TX ports are high-volume, cost-sensitive and exposed, and often fail on ESD, lightning surge and EMC. This guide explains the LAN transformer's role and key parameters from the 100BASE-TX physical layer, how ESD/surge damages the PHY, and maps VOOHU's in-stock 10/100 transformers, integrated magnetic RJ45 and GDT+TVS+ESD three-stage protection to a selection table.
RJ45 Integrated Magnetics Connector: VOOHU SYT-320DNL as a Replacement for HanRun HR911130A

VOOHU SYT-320DNL single-port RJ45 magjack replaces HanRun HR911130A: matched OCL 350µH, 1CT:1CT turns ratio, 2250V DC isolation, 16mm width and 750-cycle durability; operating temperature extended to -40 to +85°C (industrial grade), with better crosstalk and high-frequency insertion loss.
