Development and Release of a “Φ3.5mm Mini Jack (Spring Terminal)”

 We  are pleased to announce the development and release of the “Φ3.5mm mini jack (spring terminal)”.
In line with trends in recent years for small, portable equipment such as mobile phones and portable audio equipment to become smaller, thinner and more functional, demand for smaller and thinner parts with high-density mountability has increased. The Φ3.5mm jack can be installed on a wide variety of equipment, such as a connection between headphones/headphones and main unit bodies, and demand for this product is increasing.
Responding to market demands, this 4-pole type product realizes a width of 4.6mm (15% smaller than our previous equivalent 5.4mm product), contributing to an increasingly slender and compact set design.  
To support mountability to the PWB, a spring terminal system forming the terminal into a spring-shape is used, and is structured to push the terminal into the PWB when incorporated into the set. By enabling connection to the PWB without using solders, this new product provides a solder-free alternative that is kind to the environment.
