Dexerials Introduces the SFJ-21A Series: A Breakthrough in Thin-Fuse Technology

Dexerials Corporation, headquartered in Shimotsuke City, Tochigi Prefecture, has made headlines with its latest innovation – the SFJ-21A series, which is now recognized as the world’s thinnest surface mount fuse tailored for lithium-ion battery secondary protection. This impressive feat of engineering boasts a thickness of just 0.58mm, setting a new standard in the electronics industry for compactness and efficiency.

Background on Battery Innovations

With smartphones becoming ever more sophisticated and the evolution of AI technologies driving increased power consumption, the demand for efficient battery solutions has never been greater. Balancing power needs with device specifications has led to a corresponding increase in the number of lithium-ion battery cells required within mobile devices. Consequently, there is an urgent need for miniaturization and integration of components that make up these devices.

The Features of SFJ-21A Series

The SFJ-21A series comes equipped with a low resistance fuse of just 1.1mΩ, measuring 4.0mm in width and 3.0mm in height, while maintaining a groundbreaking thickness of 0.58mm. These dimensions make it ideal for use in smartphones where battery cells are on the rise but space within devices remains limited. This fuse's low resistance helps minimize heat generation and power consumption, ensuring it can easily be implemented in various applications, including not just smartphones, but also laptops.

Product Specifications

• - Model Number: SFJ-0421A
• - Number of Battery Pack Series Cells: 1 Cell
• - Rated Current: 21A
• - Fuse Resistance: 1.1mΩ
• - Dimensions: 4.0 x 3.0 x 0.58 mm (World’s Thinnest)

Having achieved a significant 31% reduction in thickness compared to previous models, the SFJ-21A not only enhances performance but also plays a crucial role in the ongoing trend towards high-functionality and component integration in mobile devices.

Commitment to Safety and Sustainability

Since the SFJ-21A series serves as a secondary protection mechanism, it is designed to activate when primary protection measures fail, stopping overcharging and overcurrent situations by melting the fuse element to break the circuit. Since its launch in 1994, Dexerials’ surface mount fuses have gained extensive application in consumer IT devices, from laptops to smartphones, significantly improving the safety of lithium-ion battery technologies.

The entire product range is lead-free, contributing to lower environmental impact and compliance with European environmental regulations (RoHS directive). As Dexerials advances its technology, it continues to focus on developing innovative surface mount fuses aimed at expanding their applications while enhancing safety standards for lithium-ion batteries.

Future Prospects

As Dexerials Corporation progresses, its aims to promote the global recognition of its products that contribute to the evolution of technology and improve the safety of lithium-ion batteries. The company is determined to maintain this trajectory by developing additional products suited for diverse applications in the market.
