Crystals Procurement Notes

Verify the specific package variant and tolerance requirements against the official CTS datasheet before ordering. Confirm that the 100 Ohm ESR specification aligns with the target oscillator circuit design to ensure proper startup and stability. Check for any recent updates to the RoHS compliance status or recommended soldering profiles in the manufacturer's documentation to guarantee process compatibility.

Crystals Selection Notes

Select this component when a 10 MHz fundamental mode crystal is required in a small 5.0mm x 3.2mm SMD package. Ensure the application circuit can accommodate a 20 pF load capacitance and that the drive level remains within safe limits for a 100 Ohm ESR device. This part is suitable for designs prioritizing standard timing accuracy over ultra-high precision requirements.

Crystals Part Context

This crystal belongs to the 435 series from CTS-Frequency Controls, which offers various fundamental mode crystals in standardized surface mount packages. The series provides options for different frequencies and tolerances, catering to general timing needs in consumer and industrial electronics where space constraints and cost-effectiveness are primary design drivers.

Crystals Replacement Considerations

Direct substitutes must match the 10 MHz frequency, ±10 ppm tolerance, 20 pF load capacitance, and 100 Ohm ESR specifications. Verify that alternative manufacturers offer identical 5.0mm x 3.2mm 2-SMD footprints and compatible operating temperature ranges to ensure mechanical and electrical interchangeability without redesign.
