Achieve Precision Stability with Harmony’s 2-in-1 Thermistor Xtal
Changes in temperature can cause a Crystal resonator (Xtal) to drift from its intended frequency, leading to inaccurate timing and synchronization. Harmony's 2-in-1 Thermistor Xtal addresses this industry challenge by integrating the Xtal and Thermistor into a single package. This enables real-time temperature feedback, ensuring precise stability over a wide temperature range while saving valuable board space.
Our 2-in-1 Thermistor Xtal simplifies circuit design and reduces part counts, resulting in cost savings and improved reliability. Fewer points of potential failure mean fewer opportunities for errors that could impact your critical applications. Our 2-in-1 Thermistor Xtal is available in sizes 2520 to 1612 and frequencies 19.2 to 76.8MHz.
Harmony's 2-in-1 Thermistor Xtal is offered in TS16949 automotive grade and tested in compliance with AEC-Q200 standards. This ensures reliable performance even in demanding automotive applications. For more information on our automotive frequency timing guide, please see our website.
Choose Harmony for the precision, stability, and compact design you need in your critical applications. Our 2-in-1 Thermistor Xtal is also offered in TS16949 automotive grade and tested in compliance with AEC-Q200 standards. See Automotive Frequency Timing guide.
