Sourced to order against BOM quantities through independent distribution, with availability and current lead times confirmed at RFQ.","metaTitle":"ASEK-32.768KHZ-L-R-S-T Abracon XO, 32.768 kHz, CMOS, 3.3V","metaDescription":"Abracon ASEK-32.768KHZ-L-R-S-T XO oscillator, 32.768 kHz CMOS output, ±25ppm stability, 3.3V supply, -40°C to 85°C, active.
