Measuring just 1.6 x 1.0mm and with a height of only 0.5mm, Interquip  32.768kHz SMLF-1610 watch crystal is ideal for applications where space on a PCB is at a premium. It is housed in a 2-pad ceramic package with an operating temperature range of -40 to +85 degrees C and a standard frequency stability coefficient of -0.03 ±0.01ppm/degrees C². Standard frequency tolerance is ±20ppm however ±10ppm can also be manufactured upon request whilst the load capacitance can be specified at 12.5pF, 9pF, 7pF or 6pF.


The SMLF-1610 is ideal for the many applications related to the Internet of Things (IoT) where accurate time keeping and non-volatile data storage is required via a Real Time Clock (RTC). These include battery management, Bluetooth, POS terminals, smart meters, wearable and Wi-Fi.
