SERVING HIGH TEMPERATURE AND DOWN HOLE APPLICATIONS
Q-Tech has long been the leader for high temperature crystal oscillators for downhole, oil and gas exploration and perforation, logging and jet engine and avionics control applications. Our high temperature products have all been rigorously qualified and are tested to the highest standards. We continue to push the state of the art including smaller size packages, lower power, current requirements, and Real Time Clock (RTC) modules.
Standard packages including ultra miniature can be supplied to withstand temperatures up to +200°C in harsh environments. Additionally, Q-Tech can provide oscillators up to +225°C in certain packages; please consult the factory. The difference between our products and our competitors’ is in our outstanding reliability, performance and quality.
