The HQST Huaqiangsheng HM82409S Gigabit Ethernet Transformer has been successfully integrated into the PCB core system of Unitree Robotics' latest Go2 intelligent robotic dog, as revealed in ChargerLAB's teardown report (#3534). This high-performance network transformer plays a pivotal role in ensuring stable, high-speed data transmission between the robotic dog's sensors, processors, and actuators.
Designed for industrial-grade reliability, the HM82409S delivers robust EMI resistance and signal integrity, critical for Go2's real-time operations in complex environments. Its compact footprint and low power consumption align seamlessly with Unitree's demand for miniaturized, energy-efficient PCB layouts. By supporting Gigabit Ethernet speeds, the transformer enables rapid communication for AI-driven navigation, obstacle avoidance, and multi-device coordination.
This collaboration highlights HQST Huaqiangsheng's expertise in developing cutting-edge magnetics for next-gen robotics. The HM82409S's deployment in Go2 underscores its adaptability to high-vibration scenarios while maintaining IEEE 802.3 compliance. As intelligent robotics advance, such components will remain vital for balancing performance, durability, and scalability in compact embedded systems.
I. Gigabit / 10 Gigabit lan Transformer Application Examples:
1.1、enterprise-class server network card: in the data centre servers of large enterprises, the network transmission speed and stability requirements are extremely high. For example, the network card used in the server series, many of which are equipped with a gigabit lan Transformer. These servers bear the enterprise's core business data processing and transmission tasks, gigabit lan Transformers can ensure high-speed, stable connection between the server network card and the network to ensure rapid data transmission and processing.
1.2, High-performance PC network card: For some PC users with high requirements for network performance, such as gamers, video editors, etc., they use high-end motherboards with integrated network cards or standalone network cards that also use gigabit lan Transformers. For example, the network card on ASUS's ROG series motherboards provides users with a smooth online gaming experience and efficient video transfer speeds through the addition of a gigabit lan Transformer.

1.3, Data centre server network card: In large-scale data centres, such as those of Google, Amazon and other companies, servers need to handle massive data transmission and exchange tasks, which requires extremely high network bandwidth. Therefore, the server network cards in these data centres commonly use 10 Gigabit lan Transformers to achieve high-speed and stable data transmission. For example, Intel's 10 Gigabit network card series is widely used in data centres.
1.4, high-performance workstation network card: for some professional graphics workstations, scientific computing workstations, etc., need to carry out a large number of data processing and transmission, the network speed requirements are also very high. The network card used by these workstations are usually equipped with a 10Gb lan Transformer to meet the demand for high-speed network.

Network card network transformers are widely used, but how to find the right product for your company to use, but also really need to have a certain understanding of the network transformer to be able to do, this section will share the relevant knowledge points, I hope you like.
A, lan transformer refers to what products?
lan transformer it a passive electronic components in the network products play isolation, anti-interference, filtering, lightning, voltage and other functions, but also network products are indispensable electronic components components.
Second, the lan transformer is also divided into integrated and separated two kinds, integrated mainly used in the PCB board empty small products, lan transformer is mainly used in switches, routers, optical cats, network cards.
