ECS-80-18-33-JGN-TR is a sub-miniature ECX-32 SMD crystal oscillator designed for compact, high-density electronic applications. The device operates at 8.000 MHz (as indicated by the "80" frequency abbreviation in the part number) with a ±20 ppm frequency tolerance at +25°C and ±20 ppm frequency stability over the -20°C to +70°C operating temperature range. It features a low-profile 3.2 × 2.5 × 0.8 mm ceramic package with a 3.2 × 2.5 mm footprint, shunt capacitance of 5 pF maximum, load capacitance of 18 pF (as specified by "18" in the part number), and maximum drive level of 100 µW. The equivalent series resistance (ESR) is 400 O maximum for the 8–9.999 MHz frequency band. This crystal is ideal for LoRa WAN, wireless communication systems, and applications requiring compact form factors with reliable frequency stability.
