Epson FC2012AN and FC3215AN quartz crystal units

Epson’s FC2012AN and FC3215AN families of quartz crystal units deliver low equivalent series resistance (ESR) and tight frequency tolerance in a compact form factor. Equipped with a crystal element based on Epson’s in-house design and decades of production technology expertise, the devices are suitable for a variety of markets and applications such as IoT, wearables, medical, industrial, security surveillance and consumer electronics.

The quartz crystal units are robust, offering a low ESR of 35 kΩ (typ) and supporting a wide operating temperature range from -40 to 105°C, which is a critical for portable electronics in space-constrained applications. In addition, the crystals deliver a fixed frequency tolerance of ±20 ppm.

The units are designed to enable the development of smaller products that use less energy. The FC2012AN is 2 x 1.2 mm in size, while the FC3215AN is 3.2 x 1.5 mm.
