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.
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.
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 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.
Main Applications
- Smartphones
- VR Goggles / VR Headsets
