Epson introduced the FC2012AN and FC3215AN –two new families of quartz crystal units that deliver very low equivalent series resistance (ESR) and extremely tight frequency tolerance in an ultra-compact form factor. Equipped with a newly redesigned crystal element based on Epson's in-house design and decades of production technology expertise, these crystals are ideal for a variety of markets and applications such as IoT, wearables, medical, industrial, security surveillance and consumer electronics. The new Epson FC2012AN and FC3215AN quartz crystal units are very robust, offering a very low ESR of 35kO (typ) and support a wide operating temperature range from -40 to 105 degrees Celsius which is a critical for portable electronics in extremely space constrained applications.

In addition, these crystals deliver a fixed frequency tolerance of ±20ppm. The FC2012AN is 2.0 x 1.2mm in size, and the FC3215AN is 3.2 x 1.5mm.
