Main Features
Feature 1: High-Speed Data Transmission of up to 25 Gbps Realizes a Movable Amount That Exceeds the Pitch Width.
The recent trends towards more sophisticated devices and an increase in the information being transmitted has spurred demand for high-speed transmission in connecting components. In addition, the increase in high-frequency components in signals has led to situations where attentions must be paid to minute details that were previously not an issue. Products compatible with High-speed transmission products are optimally designed by organically combining numerous on-site evaluations and simulations.
The 10143 series supports various transmission standards, including PCIe Gen 4, achieving*speed transmission at up to 25Gbps.
Another major feature is that it combines high reliability and ease of use by combining IRISO Electronics' floating structure technology with high-speed transmission.
*When measured according to the "OIF CEI-28G-SR" standard

Feature 2: Power Supply Terminals Contributing to Reducing the Size
By locating the power terminals on both ends of the product, there is no need to allocate terminals for power supply, contributing to reducing the size and weight of the connector.
This power terminal also serves as a fixing bracket, making it possible to miniaturize the entire connector, thereby reducing the area that the connector occupies on the board.
Feature 3: Highly Heat-Resistant Connectors for In-Vehicle Equipment
The increasing amount of heat generated around engines in in-vehicle equipment and the increasing sophistication of devices have increased the needs of connectors to have high-heat resistance.
Our highly heat-resistant products created with our material and design technology, can be used with confidence even in harsh, high-temperature environments of up to 125°C.

Wide Range of Product Variations
A wide range of products are available, with mating heights of 10 to 30 mm and pin counts ranging from 20 to 160.
Development Background
As global environmental issues have been more urgent, the global shift towards electric vehicles (EVs) has been driven by the global trend for sustainable transportation and reduced fossil fuel dependence. IRISO Electronics Co., Ltd. has been focusing on the development of connectors suitable for EV ECU devices and such to contribute to a carbon-neutral society.
We have developed BtoB connectors suitable for in-vehicle environments, helping reduce the size and weight of devices.

Mechanical Reliability
We assume misalignment within the allowable floating range and put stress on purpose at the time of maximum floating to check the occurrence of solder joint fractures. We also observe cross sections and resistance fluctuations during the test to ensure the solder joint reliability.
- Thermal shock: 0 to 100°C (Duration 15 minutes)
- Number of cycles: 3,000 cycles
- Crack Rate: See below
