Epson Announces Release of New FC1610BN Crystal Unit for Next-Generation Wearable and IoT Devices
Los Alamitos, CA – Epson, a leading global supplier of high-performance components, has announced the release of the FC1610BN 32.768 kHz crystal unit. This new crystal unit is the industry’s ultra-low power and smallest ESR quartz crystal, designed specifically for next-generation wearable and IoT devices.
Measuring just 1.6 × 1.0 × 0.5 mm, the FC1610BN crystal unit addresses one of the biggest challenges in modern electronics – delivering accurate and stable timing in ever-shrinking devices without compromising power efficiency or reliability.
According to Jonny Lee, Product Marketing Manager at Epson Microdevices, “With the FC1610BN, Epson is enabling the next wave of IoT and wearable innovation. Designers can now deliver devices that are smaller, smarter, and more responsive – without sacrificing reliability or battery life.”
The FC1610BN crystal unit boasts an exceptionally low equivalent series resistance (ESR) of ~45 kΩ at +25 °C (and ≤70 kΩ across –40 °C to +105 °C), along with a ±20 ppm frequency tolerance. This makes it ideal for use in wearables, portable medical devices, and compact IoT equipment where space, stability, and ultra-low power are crucial.
The crystal unit is available in multiple load capacitance options (7 pF, 9 pF, 12.5 pF) to support diverse design requirements. Additionally, Epson provides 3D CAD models, footprints, IBIS data, and evaluation services to help developers accelerate time-to-market.
Epson’s unique vertical integration, from manufacturing synthetic quartz crystals through advanced packaging, along with proprietary manufacturing innovations, enables the crystal’s exceptionally-low ESR and stability across extended temperatures, underpinning the FC1610BN’s performance.
By minimizing ESR, enhancing efficiency and reliability, and extending battery life, Epson’s new crystal unit empowers engineers to deliver smaller, more capable products that delight end users and stand the test of time.
