The Endura™ SiT2045 is the most reliable and the highest quality SOT23 oscillator for high-reliability aerospace and defense applications. This device delivers the perfect combination of high-frequency range (up to 137 MHz), excellent stability (±20 ppm), and wide temperature range (-55 to 125°C). Engineered for harsh environments, this oscillator features ultra-low 0.1 ppb/g acceleration sensitivity, 10,000g shock, and 70g vibration resistance. The small SOT23-5 package offers the best board-level solder joint reliability and easy optical-only, board-level inspection of solder joints.

The MEMS-based Endura SiT2045 is 100% screened through the SiTime Endura™ process flow to provide high reliability.
