About the CRH03 Series

The CRH03 is ideal for applications requiring low bias instability, low noise, and precise angle random walk. It features a proven MEMS resonating structure with enhanced balancing for robust operation in the cos2θ mode, offering strong resistance to external vibrations.

The OEM and OEM R versions are designed for enclosure-free integration. The standard OEM uses a thermistor to compensate for temperature-induced scale factor changes. In contrast, the OEM R outputs uncompensated raw data, allowing the host system to handle temperature correction using either the on-board sensor or MEMS resonant frequency. It replaces the thermistor with a precision resistor, requiring more compensation but simplifying it to a single temperature reference—unlike the OEM's three.
