Crystals Procurement Notes

Verify the specific suffix 'IDR' against the manufacturer's current datasheet to confirm packaging configuration and tape-and-reel specifications. Ensure that the required frequency tolerance of ±10 ppm aligns with system timing requirements. Confirm that the operating temperature range of -20°C to +70°C meets the environmental conditions of the final application. Cross-reference the ESR value of 60 Ohms with the oscillator circuit design to ensure proper startup and stability.

Crystals Selection Notes

Select this component when a 36 MHz fundamental frequency crystal is required in a small 2.00mm x 1.60mm footprint. The ±10 ppm stability suits applications demanding moderate precision without the cost of higher-grade oscillators. Consider the 18 pF load capacitance requirement when designing the PCB trace capacitance and MCU pin capacitance. The 4-SMD no-lead package facilitates high-volume surface mount manufacturing processes.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals, designed for general-purpose timing applications. The series offers various frequency options in standardized packages to simplify inventory management.
