DST310S 32.768KHZ 20PPM 12.5PF from KDS is a tuning-fork crystal device commonly used where stable low-frequency timing is required, such as RTC circuits, battery-powered meters, wearable electronics, industrial controls, and embedded systems. In oscillator and clock-reference applications, engineers typically select this type of component to support timekeeping accuracy while balancing power consumption, board space, and long-term design reliability. The 32.768 kHz frequency makes it especially relevant for always-on timing functions in portable and low-power products. For procurement teams, this part may be evaluated as a practical option for legacy maintenance, new design review, or second-source planning, depending on confirmed manufacturer support. Lifecycle status for this specific part is currently information not available, so design teams should verify current production status directly with KDS or an authorized distributor before committing to volume builds. RoHS compliance information is also not available in the provided data and should be confirmed through official manufacturer documentation.
