Micro Crystal Switzerland microcrystalline established in 1978, is a manufacturer of crystal tuning fork watch. Today, Micro Crystal AG is the world's leading manufacturer of miniature quartz crystals (30kHz to 250MHz), real-time clocks, oscillators and OCXOs for IoT, wearable, automotive, industrial and medical applications. As we all know, the 32.768kHz and low frequency (LF) quartz crystals produced by Swiss Micro are packaged in ceramic or metal. The tuning fork crystal has a low equivalent impedance (ESR) and a wide load capacitance (CL) range. According to the AEC-Q200 standard, these crystal products can meet the market's requirements for low-power timing devices such as oscillators or microcontrollers, high reliability, high operating temperature, and automotive application certification. Today, Jiake Crystal Electronics introduces a super practical On the clock product, the CM7V-T1A 32.768KHz crystal oscillator of the Swiss Micro Crystal brand is Micro Crystal .
This CM7V-T1A crystal oscillator has high reliability, high operating temperature, is RoHS compliant, and is 100% lead-free. This low-frequency tuning fork crystal needs to work under vacuum, so vacuum packaging is required. The maximum aging rate of CM7V-T1A crystal oscillator products is ±3x106/year and ±5x106/year, respectively. It can be used for a long time in terms of service life. The size parameters of CM7V-T1A are 3.2×1.5×0.9mm and use ultra-small thin surface mount package, which is conducive to miniaturization design. The crystal oscillator needs to be configured with filter capacitors. CM7V-T1A and configurable load capacitors of 6PF, 7PF, 9PF, and 12.5PF are used to meet all the requirements of the signal generator. The applicable fields are extremely wide, including wearables, smart watches, handheld measuring instruments, electronic multimeters, electronic scales; mobile phones, wired networks/base stations, GPS, Bluetooth, digital cameras, industrial control, automotive electronics, etc.
This 32.768K SMD CM7V-T1A crystal is designed for ultra-miniature products with strict requirements for portability applications and other applications. In addition, the high reliability of CM7V-T1A is most suitable for space-critical industrial, telecommunications, and Navigation and other specialized products. This device meets the AEC-Q200 quality standard for automotive applications. Its design is the continuation of Micro Crystal's high-reliability crystal product family. This CM7V-T1A crystal can be adapted to the temperature range from -55 to +125°C, has high accuracy (up to +/-10ppm), and meets the needs of a variety of wireless applications. The combination of low aging rate and extremely high shock and shock resistance (5000g) makes it an ideal device for high-reliability market applications. Proprietary processes are used in crystal manufacturing to achieve higher electronic characteristics with extremely small blank sizes.
