[Subversive New Product] DO33A Anti-Vibration Crystals: Cost-effective choice with uncompromising performance!
Time:2025-05-06  Read:170

In the anti-vibration crystal prices remain high in the market background, Changsha Tianqiong Electronic Technology re-launched industrial-grade DO33A type anti-vibration crystal - the same performance, the price dropped 30%! With a more affordable price, to provide high-grade anti-vibration protection for your equipment!


Basic description:


DO33A adopts high quality SC-cut quartz crystal, built-in low phase noise vibration circuit and high-precision temperature control circuit, which can generate low phase noise signal. Adopting the company's unique patented airbag vibration damping structure and anti-aging materials, it realizes the anti-vibration capability under any vibration conditions, especially for the occasions with strict requirements on phase noise at the far end.


Specification parameters:


Size: 33*30*20mm;


Output frequency: 100MHz


Operating temperature range: -40 degrees ~ +70 degrees;


Initial frequency accuracy: 0.5ppm;


Frequency temperature coefficient: 0.5ppm;


Phase noise: < -158dBc/Hz@1kHz

Why DO33A is the king of cost performance?


✅ Performance against international high-end products


◆ Remote super vibration resistance: phase noise ≤ -150dBc/Hz (1kHz) under three-axis vibration test, far beyond similar competitors;


◆ Wide temperature domain stability: static/dynamic phase noise under -40℃~+70℃ environment are ≤ -150dBc@1kHz, adapting to extreme environment;


◆ High-frequency customization freedom: support 10MHz~160MHz frequency flexible options to meet the needs of multiple scenarios.



✅ 30% direct price reduction, breaking the industry's high price barriers

We have upgraded the supply chain through localization and technological innovation to reduce costs, so that high-performance anti-vibration crystals are no longer out of reach! Under the same parameters, the price of DO33A is only 70% of similar products in the market, helping you to significantly reduce equipment costs!

The cost performance of DO33A is far beyond expectation! During the UAV flight test, the vibration

interference caused the observation error to increase, but after using DO33A, the observation error

 remained zero throughout the whole process.
