TKD, a leading domestic quartz crystal manufacturer, offers quartz crystal resonators renowned for their miniaturization, high precision, and exceptional reliability. These products are widely deployed in smart electricity meters, 5G communications, optical modules, automotive electronics, and other critical sectors.
TKD tuning fork crystal resonators (32.768kHz) utilize advanced photolithography technology, featuring ultra-low power consumption and miniaturized packaging, making them ideal for smart wearables, high-precision RTC, smart meters, and IoT devices. TKD MHz crystal resonators offer extremely low Equivalent Series Resistance (ESR) and excellent phase noise performance, with ultra-compact packages (as small as 1.6×1.2mm), widely used in 5G communications, optical modules, automotive electronics, and other high-speed applications. TKD thermistor crystal resonators integrate temperature compensation functionality for stable operation over wide temperature ranges, with 76.8MHz high-frequency products having passed Qualcomm automotive-grade certification for use in premium new energy vehicles.
TKD's full line of automotive-grade crystal resonators has successfully passed AEC-Q200/Q100 certifications from authoritative third-party organizations, serving as the essential "passport" for entry into automotive supply chains. The company operates the industry's only dedicated automotive-grade production line and a CNAS-accredited laboratory, strictly following AEC-Q200 standards for full lifecycle reliability verification. The products feature exceptional shock and vibration resistance, with an operating temperature range from -40℃ to +125℃ and an annual aging rate as low as ±3ppm/year. Over 2,000 automotive-grade product part numbers have been developed, covering all five automotive electronic domains.
TKD MHz crystal resonators leverage self-developed MEMS photolithography and crystal structure optimization to achieve industry-leading ESR performance. Typical ESR values can be as low as 20Ω to 40Ω (e.g., 20Ω for 40MHz products, 30Ω for 26MHz products). In terms of frequency precision, room temperature frequency tolerance can reach ±10ppm, with some products supporting ±20ppm options. Ultra-low ESR enables faster oscillator start-up and lower power consumption, making these resonators particularly suitable for high-speed applications such as 5G communications and optical modules that demand stringent signal integrity and start-up time.
TKD thermistor crystal resonators integrate a built-in thermistor and employ a self-developed temperature compensation algorithm to automatically compensate for temperature drift. They maintain a high frequency stability of ±0.5ppm over a wide temperature range from -40℃ to +105℃, with temperature hysteresis below ±0.05ppm. Select automotive-grade products can operate reliably in extreme temperature environments up to 115℃. These products have passed Qualcomm automotive-grade certification (SA522/SA525 platforms), with 76.8MHz high-frequency thermistor crystal resonators successfully deployed in ADAS, smart cockpits, and other core automotive electronic systems.
