ATS040SM-1 Description

Short technical summary and product information.

The ATS040SM-1 is a fundamental mode quartz crystal from the ATS/ATS-SM series by CTS-Frequency Controls. It operates at a nominal frequency of 4 MHz with a load capacitance of 20 pF, providing a frequency tolerance of ±30 ppm and frequency stability of ±50 ppm over the -20°C to 70°C temperature range. The maximum equivalent series resistance (ESR) is 120 Ω, making it suitable for low-power oscillator circuits.

 

The crystal is housed in a standard HC-49/US surface mount metal package, measuring 11.10 mm x 4.83 mm x 4.30 mm. It is designed for automated assembly and is compatible with reflow soldering processes. Typical applications include wireless communications, broadband access, FPGA/microcontrollers, computer peripherals, test and measurement, consumer electronics, and portable equipment. The component is specified for use in commercial and industrial environments.
