ECS-120-20-3X-TR Description

Short technical summary and product information.

The ECS-120-20-3X-TR is a 12 MHz fundamental mode quartz crystal from ECS Inc.'s CSM-3X series. It offers a frequency tolerance of ±30 ppm at +25°C and frequency stability of ±50 ppm over the operating temperature range of -10°C to +70°C. The crystal is designed for a load capacitance of 20 pF and features a maximum equivalent series resistance (ESR) of 60 Ω.

 

This surface mount device is housed in a miniature low-profile HC-49/US package measuring 7.00 mm x 4.10 mm x 2.30 mm. It is supplied on tape and reel with a standard quantity of 3000 pieces per reel. The crystal is RoHS compliant and lead-free, with an MSL rating of 1 (unlimited).

 

Typical applications include timing circuits in consumer electronics, industrial controls, and communication equipment where a stable and reliable clock source is required. The CSM-3X series reduces footprint by 50% compared to the CSM-7X (HC-49USX SMD) package.
