IQD Frequency Products Ltd

Measuring just 2.0 x 1.2mm and with a height of only 0.6mm, IQD's 32.768kHz IQXC-25 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 IQXC-25 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, wearables and Wi-Fi.

The standard part numbers are: LFXTAL050789 (12.5pF), LFXTAL051643 (9pF), LFXTAL059461 (7pF) and LFXTAL065455 (6pF) and these are available on Tape and Reel (REEL) or on Cut Tape (CUTT). All variants are available either direct from IQD or via our extensive range of worldwide distributors with live stock visibility available on our website at www.iqdfrequencyproducts.com.
