描述

The 26-JX2F12.5-32.768KHZ is a 2 lead metal package crystal in a 2 mm × 6 mm form factor, designed for low-frequency timing applications requiring high stability and precision. This crystal operates at 32.768 kHz in fundamental mode with a load capacitance of 12.5 pF standard, featuring an X-cut design that provides excellent temperature stability with a parabolic coefficient of -0.034 ppm/°C² typical. The device exhibits an equivalent series resistance (ESR) of 35 kO maximum in the 32–39.9 kHz range, frequency tolerance of ±20 ppm at 25°C, and aging of ±5 ppm per year, with operating temperature range from -40°C to +85°C. The crystal is lead-free and RoHS compliant, making it suitable for real-time clocks, metering systems, industrial control applications, and time reference circuits where compact size and reliable long-term performance are essential.
