Hqst Electronics H81601S lan Ethernet Transformers
The Hqst Electronics H81601S is a single port 10/100 BASE-T SMT (Surface Mount Technology) PoE+ (Power over Ethernet Plus) 16-pin Ethernet transformer module designed for network communication devices. Corresponding to POSI's H1102NL,The module is suitable for applications such as IP telephony, wireless access points, security cameras, etc. that require simultaneous transmission of data and power over Ethernet cables.

The H81601S module integrates a high-performance transformer and filtering components designed to provide stable signal transmission and efficient power delivery. It supports the IEEE 802.3af/at standard and is capable of being compatible with PoE (Power over Ethernet) and PoE+ protocols, which means it can power devices that require higher power outputs of up to 25.5 W. This makes the H81601S ideal for network devices that have high power requirements but want to simplify the installation process.
In terms of physical features, the H81601S is available in a 16-pin SMT package for easy integration with various motherboards and other circuit boards. Its compact design not only saves space, but also improves system reliability, especially when operating in harsh environments such as high temperature or high humidity. In addition, the module has good electromagnetic compatibility (EMC), which reduces interference and ensures the stability and integrity of data transmission.
From an application perspective, the H81601S is not limited to traditional networking devices. With the development of the Internet of Things (IoT), more and more smart devices require Ethernet connectivity for remote control and data exchange. These devices are often located in locations where it is difficult to install a separate power source, making the use of Ethernet cables to transmit both data and power an efficient and cost-effective solution, and the H81601S has been developed to meet the market's need for a compact, high-performance, and multi-functional Ethernet transformer module.
In short, the Hqst Electronics H81601S is one of the products of choice for many network equipment manufacturers and system integrators due to its outstanding performance, reliability and flexibility. Whether it is for enhancing the competitiveness of an existing product or developing a new generation of intelligent devices, the H81601S provides strong technical support.
