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!
