Crystals Procurement Notes

Verify the specific load capacitance requirement of 13pF against the target circuit design to ensure accurate oscillation frequency. Confirm that the ESR value of 40 Ohms aligns with the oscillator driver strength specifications. Ensure the operating temperature range of -20°C to +70°C meets the environmental requirements of the final application before integration.

Crystals Selection Notes

Select this component when a 44 MHz fundamental frequency is required in a compact surface-mount form factor. The 13pF load capacitance specification distinguishes it from other variants in the 405 series. Consider the ±30ppm tolerance for applications requiring moderate frequency precision without the need for higher-grade stability options.
