Q13FC1350000200 crystal oscillator is the best solution for detection systems

    Air filter element, also known as air filter element. Mainly used for air filtration in construction vehicles, automobiles, and various precision operating rooms. When the air filter element is damaged or used for a period of time, it will have a certain impact on the filtering effect, causing some dust to be sucked into the cylinder. Our air filter detection system is designed to detect PM2.5 levels in the filter cartridge. When the indicator is exceeded, it indicates that the air filter element is damaged or aged. At this point, the detection system will report the detected data and alarm information to the mobile app, reminding users to check and replace the air filter in a timely manner. The air filter detection device designed by the author uses Epson crystal oscillator FC-135 32.768KHz passive Q13FC1350000200 as the main chip to ensure accurate timing and stable operation of the system, realizing the detection of PM2.5 values in the air filter and reporting to the mobile phone.

    This FC-135 code Q13FC1350000200 crystal oscillator has a load capacitance of 7pF, a typical ESR value of 55k Ω, and a maximum ESR value of 70k Ω, which is within the recommended range in the specification sheet; The frequency tolerance is extremely low, ranging from 20ppm to 250ppm; C0=1PF, DL=0.1 μ W are also within the recommended range in the specification sheet. Overall, EPSON's 32.768k crystal oscillator Q13FC1350000200 parameter specifications fully meet the product design requirements. In addition, this crystal oscillator has a temperature range of -55 ℃ to+125 ℃ and is packaged in a small size of 3.2 * 1.5mm, which can meet the requirements of small-sized product design.

    The CL of Q13FC13500002000 crystal oscillator is 7pF. When wiring, attention should be paid to the calculation of parasitic capacitance (CS) on the printed circuit board. Generally, it should be controlled at around 2pF. Calculated according to 2pF: CL1=Cl2=10pF. In the process of selecting Epson 32.768KHz or other frequency crystals, we can first communicate project requirements with the technical support personnel of Jiake Electronics, and the technical personnel will recommend the most suitable model based on customer needs. At the same time, they can also provide PCBA to Epson for testing and selecting the best crystal oscillators and external load capacitors. Epson's 32.768KHz crystal Q13FC1350000200 is widely used in mobile phones, tablets, smart homes, medical electronics, and smart wearable devices.
