• Compact 4-SMD no-lead surface mount footprint
• Low equivalent series resistance of 60 Ohms
• RoHS3 compliant environmental construction

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Embedded system oscillator circuits
• Consumer electronics timing control

Crystals Procurement Notes

Verify the specific suffix CKT against official datasheets to confirm packaging type and tape/reel specifications. Ensure compatibility with existing PCB footprints matching the 2.00mm x 1.60mm dimensions. Confirm that the ±10ppm stability meets system requirements before integration. Check current availability status as lead times may vary by distributor.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency is required with tight ±10ppm stability. The 8pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for drive level sensitivity. The -20°C to +70°C range suits general commercial environments. Verify package compatibility with automated assembly processes.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. These legacy products provide mature timing solutions but are generally not recommended for new designs. The series offers various frequencies and packages within the same physical form factor family.

Crystals Replacement Considerations

CTS recommends evaluating updated frequency control products for new designs rather than using legacy parts. Cross-reference with other manufacturers offering 38.4 MHz SMD crystals with identical 8pF load and 60 Ohm ESR specifications if substitution is necessary.
