Resonators Procurement Notes

Verify the specific suffix G53 corresponds to the required 15 pF load capacitance and 4.43 MHz frequency during procurement. Confirm that the SMD package dimensions align with the PCB footprint requirements. Ensure the operating temperature range of -20°C to +80°C meets the environmental specifications of the target application before finalizing orders.

Resonators Selection Notes

Select this component when a stable, low-cost alternative to crystal oscillators is required for microcontroller systems. The integrated design simplifies layout by reducing component count. Consider the ±0.5% tolerance for applications requiring precise timing. Evaluate the 15 pF load capacitance compatibility with the host MCU's internal capacitors to ensure accurate frequency operation without external adjustments.

Resonators Part Context

This part belongs to Murata’s CERALOCK CSTCR series, which specializes in small-cap chip type ceramic resonators. These components are engineered to replace traditional quartz crystals in cost-sensitive designs.
