World's smallest 32.768kHz watch crystal, measures just 1.6mm x 1mm x 0.5mm

AEL Crystals has made significant progress in reducing the size of the core technology for wearable and IOT devices, with its three latest product introductions: the 1610 watch crystal; the 1210 crystal; and the 1612 oscillator. The 1610 watch crystal is the world's smallest 32.768kHz crystal, measuring just 1.6mm x 1.0mm x 0.5mm (max). It is available with wide operating temperature ranges up to -40C to +105C and is robust and reliable in operation, initial stabilities can be specified between +/-10 and +/-50ppm , making it suitable for wireless modules, in-car devices, Bluetooth devices and mobile phones, as well as wearable devices, such as smart watches, fitness trackers, medical and activity monitoring devices etc. For reliable operation, the ESR (Equivalent Series Resistance) is 60kohm (Max), making the 1610 watch crystal particularly suitable for low ESR applications such as Bluetooth Low Energy chipsets. Furthermore, AEC-Q200 compliant versions are available, making it ideal for use in the automotive industry. The 1210 crystal is the world's smallest crystal and measures just 1.2mm x 1mm x 0.33mm (max). It can be supplied between 36.0 and 80.0MHz. Operating temperature can be specified up to -40C to +125C, with temperature stability from +/-10 to +/-50ppm and initial stability as low as +/-7ppm. AEC-Q200 compliant versions are also available. The world's smallest oscillator is the 1612. It measures just 1.6mm x 1.2mm x 0.7mm (max) and operates across a temperature range from -40C to +85C. It is reliable, with a temperature stability of +/-10 to +/-50ppm, and initial stability of +/-7 to +/-50ppm. Additionally, it has a wide operating frequency range of 1.0 to 80.0MHz and operates from a 1.8, 2.5 or 3.3V supply, says the company.
