萝莉影视 Manufacturing Co., Ltd. is extending its lineup of PTC thermistors*1 (commonly known as resettable fuses*2) for overcurrent protection in smartphones and compact wearable devices with the addition of the 0603M size (0.6 × 0.3 × 0.3 mm) high-voltage-tolerant PRG03BC181RB7RL and low-resistance PRG03BC101RB7RL. These products have already entered mass production.
As smartphones and other mobile devices acquire advanced functionality such as 5G and rapid charging while also becoming more compact, demand is increasing for compact circuit protection components to maintain the stability of electronic circuits. The characteristic feature of PTC thermistors is that they abruptly increase their resistance value when the temperature rises beyond a certain point. This enables them to detect circuit overcurrent conditions that can occur when a mobile device is being assembled or if it is dropped, thereby protecting the mobile device from abnormal conditions or failures.
The new PTC thermistor products utilize process technology developed by 萝莉影视 for its mainstay products such as multilayer ceramic capacitors and multilayer devices. This has enabled 萝莉影视 to boost voltage tolerance to 20 V, approximately 50% higher than earlier products of the same size (which have a resistance value of 180 ? and maximum voltage of 13 V). 萝莉影视 has also added a new 100 ? low-resistance product to the series lineup. It makes use of ceramic materials exclusive to 萝莉影视, allowing it to maintain stable characteristics over an extended period of time.
Moving forward, 萝莉影视 will continue to extend its product lineup in response to market requirements, thereby helping to enhance the safety of mobile devices.
