Ultra small crystal oscillator FC2012SN used in wearable devices

    In recent years, smart electronic devices such as smartphones, wearable devices, and IoT devices have rapidly become popular. Moreover, in order to improve the design flexibility and wearable comfort of the products and ensure the space required for configuring new features, it is required that the size and power consumption of the components installed on these products be reduced to the limit. Taking crystal oscillators as an example, in the era before the rise of smart hardware, 3225 surface mount crystal oscillators were widely used, and 2520 can be considered a relatively small passive crystal oscillator package. Nowadays, passive crystal oscillators used in smart products are mostly 1612 surface mount oscillators, with 2012 surface mount oscillators being the main ones. These crystal oscillators, due to their small size, require magnifying glasses or even microscopes to see their true faces clearly. If electronic components are uniformly reduced in size, the spacing between them will also be shortened. This has the advantage of reducing the capacitance of different transistor terminals, thereby increasing their switching frequency. Because the dynamic power consumption of each transistor when switching electronic signals is directly related to the current capacity, it accelerates the operating speed and reduces energy consumption. The smaller the size of the components, the higher the integration of the processor, resulting in higher flexibility and lower power consumption of the processor.

The Epson FC2012SN crystal oscillator not only meets the miniaturization requirements of various smart terminals in terms of external dimensions, but also has energy-saving, power-saving, and high-efficiency characteristics. In the working environment, this product is more resistant to vibration and heat, with a maximum temperature tolerance of 105 degrees Celsius. The crystal oscillator with a volume of 2012mm can be said to be a blessing for small digital products at present. The small quartz crystal oscillator is currently used in ultra small smartphones. This product is most suitable for wireless communication systems, wireless local area networks, and has achieved low phase noise, low voltage, low consumption current, high stability, ultra small, lightweight and other product characteristics. The product itself comes with a packaging method that can correspond to automatic high-speed surface mount machines and high-temperature reflow soldering (lead-free corresponding to the product), making it a lead-free product。

The EPSON high-temperature resistant crystal oscillator FC2012SN has a frequency of 32.768KHz, a small volume crystal oscillator size of 2.05x1.2x0.6mm, a two pin surface mount crystal oscillator, a passive crystal oscillator, and a quartz crystal resonator. FC2010SN is a product developed as a follow-up model of FC-12M. Its characteristic is a better working temperature range than FC-12M, supporting up to+105 ℃. It is an ideal application, such as IoT devices, expected to expand and FA devices working at high temperatures. Epson is a leading supplier of KHz band crystal units, providing built-in oscillation circuits and real-time clock modules in addition to crystal units. Application: Wearable devices, MCU used for sub clocks, Bluetooth crystal oscillators, wireless module sub clocks, FA devices, smart watches, computers, instrumentation equipment, digital electronics and other applications.
