Crystals Procurement Notes

Verify the specific suffix D against manufacturer documentation to confirm package and tolerance variations. Ensure the design-in process accounts for the 18pF load capacitance requirement to maintain frequency accuracy. Cross-reference the 407 series datasheet for soldering profile recommendations compatible with the 4-SMD leadless form factor.

Crystals Selection Notes

Select this component when a 44.736 MHz fundamental frequency is required with moderate stability specifications. The 407 series offers a balance between size and performance suitable for general-purpose timing circuits. Consider the 40 Ohm ESR value when designing the oscillator circuit to ensure adequate loop gain and reliable startup conditions.

Crystals Part Context

This part belongs to the CTS 407 series of surface-mount crystals, which are engineered for cost-effective timing solutions. The series utilizes standard AT-cut quartz resonators encapsulated in small outline packages. It serves as a common alternative to through-hole variants where space constraints dictate the use of SMD components.
