KYOCERA 5908 Series | Advancing High-Speed Connectivity

Innovative Shielded Board-to-Board Connectors for Reliable EMI Protection

Kyocera Corporation (President: Hideo Tanimoto) has developed the 0.4 mm pitch 5908 Series board-to-board connector, which is the first in its lineup to feature a fully shielded structure. Sales of this product, which enhances EMI characteristics by suppressing electromagnetic interference and supports high-speed transmission, began on Thursday, July 31. 2025

As communication and information processing technologies advance, devices such as smartphones and smartwatches require increasingly sophisticated connectors. Enhancing EMI characteristics during high-speed transmission has become a significant challenge for these applications.

Kyocera addressed this challenge by introducing a fully shielded structure in the 0.4 mm pitch 5908 Series board-to-board connector, which effectively suppresses noise intrusion and leakage, offering excellent EMI characteristics.

1. Fully shielded structure provides excellent EMI characteristics, supporting high-speed transmission

A fully shielded structure has been adopted, in which the outer circumference of both the plug side
and the receptacle side is covered with a conductive metal (Figure 1). Since the fully shielded structure covers the main body and mating area of the connector with a metal shell, it can maximally suppress the intrusion and leakage of noise, thereby improving EMI characteristics. When mated, this product forms a double-shielded structure, allowing the electrical signal circuits to pass through the shield, which suppresses noise generation (Figure 2).

Supports high-speed transmission standards | PCI Express^*3 Gen.3 (8Gbps) and USB^*4 3.2 Gen.2 (10Gbps), etc.

2. Unique locking mechanism increases robustness and improves retention force by 30% | Both components also feature an R-shaped design to facilitate assembly and enhance workability.

The plug features a convex shape and the receptacle a concave shape, creating a locking structure that ensures secure mating and increases retention force by 30% compared to our previous products. Both components also feature an R-shaped design to facilitate assembly and enhance workability.

• *1 – A structure in which both the outer circumference of the connector’s plug side and receptacle side are covered with conductive metal.
• *2 – Electromagnetic Interference: Characteristics regarding the amount of electromagnetic interference generated and the resistance to such interference.
• *3 – PCI Express (PCIe): A high-speed serial bus standard for connecting internal expansion cards (such as graphics boards and SSDs) to the motherboard of a personal computer.
• *4 – USB: A general-purpose interface for connecting personal computers and peripheral devices (such as mice, keyboards, and storage devices).
