The ATS16B-E is a 16.000 MHz thru-hole quartz crystal designed for reliable performance in demanding environments. It operates in fundamental mode with a specified load capacitance of 18 pF and a maximum equivalent series resistance (ESR) of 40 Ohms. This AT-cut crystal features a standard frequency tolerance of ±30 ppm at 25°C and a frequency stability of ±50 ppm across its extended operating temperature range of -40°C to +85°C. Housed in a proven HC-49/US metal package, it is ideal for microprocessor timing, telecommunication, industrial, and consumer electronics applications.
