Quartz Crystals kHz

32.768 kHz Watch Crystals

A 32.768 kHz watch crystal is widely used as a timing reference for clocks and RTCs. Its frequency can be divided down to produce a one-second timebase, making it suitable for timekeeping in watches and many battery-powered electronic devices.

IQD offers both tuning fork and AT-cut 32.768 kHz crystals. The best option depends on the required stability and other design constraints. IQD also offers additional frequencies across its kHz quartz crystal range.

Quartz crystal features and options

Depending on the selected part number, IQD kHz quartz crystals are available with:

• Frequencies from 10 kHz to 2,500 kHz
• Package sizes starting at 1.2 × 1.0 mm
• Frequency tolerances down to ±10 ppm
• A range of operating temperature options
• Low-height and surface-mount (SMD) packages
• Through-hole (THT) options for legacy designs
• High shock resistance and low ageing
• Made-to-order and customisable options

Find the right crystal for your design

When selecting a quartz crystal, consider the required frequency, frequency tolerance, operating temperature, package dimensions and environmental conditions. These requirements vary by application and product, so check the individual datasheet when comparing options. App Note | How to Specify Quartz Crystals
