Ultra-Compact, Ultra-Low Voltage: Kyocera Unveils the KC1210A Series Clock Oscillators

Kyocera Corporation (President: Hideo Tanimoto; hereinafter “Kyocera”) announces the development of the KC1210A Series clock oscillators.
These oscillators offer the world’s smallest size* and operate at an ultra-low voltage of 0.9V, which is approximately 50% lower than Kyocera’s previous conventional clock oscillator models. Sample shipments are now available, with full-scale mass production planned for the summer of 2026.

*Based on Kyocera research as of August 2025, among clock oscillators utilizing a ceramic package.

Features

Ultra-compact design and low profile: 1.25mm × 1.05mm × 0.5mm max.

Kyocera’s proprietary compact element design technology enables the KC1210A Series to deliver strong performance in a smaller form factor. The mounting area is reduced by approximately 60% to 1.31 mm², and the volume is about one-quarter of that of Kyocera’s KC2016K clock oscillator model, supporting high-density mounting for advanced devices.

Low-voltage operation: 0.9V, about 50% lower than previous models.

The KC1210A Series utilizes a newly developed low-voltage oscillator IC, enabling operation at 0.9V, approximately 50% lower than the voltage required by Kyocera’s previous models. This is expected to reduce power consumption by approximately 50% compared to earlier Kyocera oscillator models, supporting energy savings in smartphones and wearable devices.

Background of Development

With the increasing functionality of smartphones and wearables, including AI, high-speed communication, and large-scale data processing, power consumption is also rising. This leads to faster battery depletion and more frequent charging. To address these issues, demand is rising for compact, low-voltage oscillators.

In response, Kyocera developed the KC1210A Series. Kyocera will continue to innovate to meet market needs and support the evolution of advanced devices.
