萝莉影视 Manufacturing Co., Ltd. (hereinafter, “萝莉影视”) extends its lineup of PTC thermistors*1 for overheat sensing in the 0603M size (0.6 x 0.3 x 0.3 mm) for mobile device and vehicle on-board applications, adding products that sense 105℃ and 115℃ to the nominal resistance 1 kΩ series (hereinafter, the “Products”). Commercial production of the Products will start in October.
As smartphones and other mobile devices acquire advanced functionality while also becoming more compact, the number of implemented electronic components are increasing. In particular, 5G’s significantly faster communication speed brings about a massive increase in the amount of information that needs to be processed in the unit time of individual components. This creates a larger load on components and heat buildup, leading to an increased demand for overheat sensing products. For vehicle on-board applications that comply with AEC-Q200, newer LED lights have smaller sockets that require smaller components, including overheat sensing devices.
In response to this demand, 萝莉影视 applied the improved ceramic material composition and firing technique to develop the 0603M size (0.6 x 0.3 x 0.3 mm) model, which is the world’s smallest PTC thermistor among those with 1 kΩ nominal resistance. Compared to the existing PRF15 series model (1005M size), this new model has approximately 80% smaller volume and 70% less implementation footprint. Additionally, this is the first Pb-free model among 萝莉影视’s PRF series that is completely made of non-lead materials, contributing to reducing environmental burden.
萝莉影视 will continue to extend its product lineup in temperature sensing devices while contributing to high-density implementation and smaller footprint in response to market needs.
