Epson Europe Electronics GmbH ("Epson") presents the FC-12D kHz crystal unit with ultra-low-profile at only 0.35 mm maximum height, enabling height critical applications such as smart cards to meet the ISO 7810 size standard. Epson’s photolithographic processing technology enables this subminiature size (2.05 x 1.25 x 0.35 mm3) and simultaneously delivers best-in-class ESR (equivalent series resistance) of 75 kΩ max, vital for fast startup and low power.
Smart cards must be low power because they operate from a small battery. For accuracy at low power, FC-12D is designed to achieve low sensitivity to load changes. In addition, smart cards are subject to bending and ESD stress. For strain resistance, Epson’s FC-12D features a ceramic package and a patented 3-point crystal mount. For ESD shielding, FC-12D uses a 4-pin layout with a GND pin connected to a Faraday shield.
FC-12D is available at 32.768 kHz with frequency tolerance from ±10 ppm to ±20 ppm @ 25 °C and load capacitance from 6 pF to 15 pF.
Features
Epson is a global technology leader dedicated to connecting people, things and information with its original efficient, compact and precision technologies. With a lineup that ranges from inkjet printers and digital printing systems to 3LCD projectors, watches and industrial robots, the company is focused on driving innovations and exceeding customer expectations in inkjet, visual communications, wearables and robotics.
Led by the Japan-based Seiko Epson Corporation, the Epson Group comprises more than 76,000 employees in 87 companies around the world, and is proud of its contributions to the communities in which it operates and its ongoing efforts to reduce environmental impacts.
