ECS-.327-6-34RR-TR Description

Short technical summary and product information.

The ECS-.327-6-34RR-TR is a tuning fork crystal from the ECX-34RR series, providing a nominal frequency of 32.768 kHz. It is designed for surface-mount assembly in a compact 3.2 mm x 1.5 mm package with a low profile of 0.9 mm, making it suitable for space-constrained designs.

 

Key electrical specifications include a frequency tolerance of ±20 ppm at +25°C, a load capacitance of 6 pF, and a typical equivalent series resistance (ESR) of 20 kΩ. The crystal operates over a temperature range of -40°C to +85°C and features a turnover temperature between +20°C and +30°C with a temperature coefficient of -0.034 ppm/°C².

 

The device operates in fundamental mode and is rated for a drive level of 0.1 µW, with a maximum of 0.5 µW. First-year aging is limited to ±3 ppm. The component is supplied in tape-and-reel packaging with a standard quantity of 3000 pieces per reel, suitable for automated assembly.
