32.768kHz Tuning Fork Crystals for RTC & Timing Applications

32.768 kHz crystal resonators serve as the reference timing source for ultra-low-power Real-Time Clock (RTC) circuits. They are widely used in smartphones, smartwatches, security & surveillance systems, IoT devices, industrial control equipment, and other electronic products that require precise timekeeping with minimal power consumption.

SJK provides a complete range of 32.768 kHz crystal solutions to meet various application requirements. Our product portfolio includes traditional cylindrical through-hole packages (2 × 6 mm and 3 × 8 mm), as well as our flagship miniature high-precision SMD crystal resonators, available in 1610, 2012, 3215 (CM-315 compatible), and 7015 (MC-146 compatible) package sizes.

Multiple load capacitance options are available, including 6 pF, 7 pF, 9 pF, and 12.5 pF, with standard frequency tolerances of ±10 ppm and ±20 ppm. We also support automotive-grade (IATF 16949) customized specifications to satisfy demanding automotive and industrial applications.

PDF datasheets are available for download across the entire product range. SJK also offers free sample requests, reliable supply chain support, and fast delivery to help accelerate your product development.
