ECX-16 Low ESR 32.768 kHz Tuning Fork Crystal
The ECX-16 compact 32.768 kHz tuning fork crystal offers a low ESR, tight frequency tolerance options and extended temperature ranges making it ideal for the STM32 Microcontrollers.
The ECX-16 series of tuning forks come in a 1.6 mm x 1.0 mm x 0.5 mm 2-pad ceramic package. The ECX-16 offers and ESR of 90 kΩ and a standard frequency tolerance of ±20 ppm at 25ºC with a tight ±7 ppm option available. This electronic component offers standard load capacitance options of 5pF, 6pF, 7pF, 9pF and 12.5pF all over the industrial operating temperature of -40ºC to +85ºC. The ECX-16 tuning forks are ideal for mobile devices, wearable and consumer applications. Because of the low ESR, they are recommended by STMicroelectronics for the STM32 Microcontrollers via the AN2867.
