ECS-120-18-33-JEM-TR Description

Short technical summary and product information.

The ECS-120-18-33-JEM-TR is a 12 MHz fundamental mode quartz crystal from ECS Inc., part of the ECX-32 series. It offers a frequency tolerance of ±20ppm and frequency stability of ±50ppm over the operating temperature range of -20°C to 70°C. The crystal is designed for a load capacitance of 18pF and has a maximum equivalent series resistance (ESR) of 100Ω.

 

This crystal is housed in a compact 4-SMD, no lead package measuring 3.20mm x 2.50mm with a low profile height of 0.80mm, making it suitable for space-constrained surface mount applications. The package code is 33, and the device operates in fundamental mode.

 

Typical applications include timing reference circuits in consumer electronics, industrial controls, and communication devices where a stable 12 MHz clock source is required. The part is RoHS3 compliant and has an MSL rating of 1 (unlimited).
