FAQ
Common Questions About Tuning Fork Crystals
Why is the frequency always 32.768kHz for tuning fork crystals?
32.768kHz = 2^15 Hz, allowing a simple 15‑stage binary divider to produce a precise 1Hz signal for RTC applications. The tuning fork shape provides very low power consumption.
What load capacitance do I need for my RTC?
Check your RTC datasheet. Common values: 6pF, 7pF, 12.5pF. Using the correct CL ensures accurate frequency. For CL=12.5pF and stray≈2pF, use external capacitors C1=C2=20pF.
What is the difference between cylinder DIP and SMD tuning fork crystals?
Cylinder DIP (2×6mm, 3×8mm) are through‑hole, easier for prototyping. SMD versions (ceramic or plastic) are for automated assembly.
Do you offer AEC‑Q200 automotive grade tuning fork crystals?
Yes, specific models (especially XD ceramic SMD series) are available with AEC‑Q200 qualification for automotive applications.
What is the typical lead time and MOQ?
Standard MOQ: 1,000 pieces. Lead time: 2‑3 weeks. Free samples available for qualified projects. Contact sales@vistarelectronics.com.
