Key Features
Ultra-compact design and low profile: 1.25mm × 1.05mm × 0.5mm max.
Low-voltage operation: 0.9V, about 50% lower than previous models.
Kyocera Corporation (President: Hideo Tanimoto; hereinafter “Kyocera”) announces the development of the KC1210A Series clock oscillators. These oscillators offer the world’s smallest size*1 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.
Background of Development
With the increasing functionality of smartphones and wearables, including AI, high-speed communication, large-scale data processing, and power consumption are 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 has developed the KC1210A Series and will continue to innovate to meet market needs and support the evolution of advanced devices.
■ Features of the KC1210A Series
1. Ultra-compact design and low profile: 1.25mm × 1.05mm × 0.5mm max.
Kyocera’s proprietary compact element design technology*2 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.

2. 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.
