TB4 Series High-Reliability 125°C FPC/FFC-to-Board Connectors

HIROSE Electric Co., Ltd., a world-class innovator in connector technology, presents the TB4 Series, a next-generation FPC/FFC-to-Board connector designed specifically for the rigorous demands of automotive electronics.
Engineered with durability and safety in mind, the TB4 Series meets USCAR-2 compliance and operates reliably at temperatures up to 125°C, making it suitable for placement in challenging environments, including near engine compartments. Its robust structure and premium materials ensure long-term reliability even under harsh conditions.
The connector’s two-piece structure enables seamless assembly by simply inserting the FPC/FFC into the plug housing and securing it with a retainer. This innovative design not only improves assembly efficiency but also provides mechanical stability and terminal position assurance, eliminating the need for traditional terminals. The result is reduced weight, space savings, and increased reliability—an ideal solution for compact automotive systems.
With a 1.0 mm pitch and a low profile of just 4.5 mm, the TB4 Series optimizes space without compromising performance. Its guide key design prevents misalignment and damage caused by incorrect insertion, ensuring smooth and secure mating.
Operator safety is a key feature of the TB4. The receptacle incorporates finger protection, preventing accidental contact with conductive parts, while the plug’s protective guide structure shields terminals from damage and minimizes the risk of electric shock.
The TB4 Series delivers reliability, compactness, and safety—making it the perfect choice for advanced automotive applications requiring secure FPC/FFC-to-Board connections.
