Crystals Procurement Notes

Verify the specific suffix 'IAR' against the manufacturer's current datasheet to confirm package orientation and lead finish specifications. Ensure the design accommodates the 4-SMD no-lead form factor and 8pF load capacitance requirements. Confirm availability status as distribution channels may vary. Cross-reference the ESR value of 60 Ohms with oscillator circuit designs to ensure proper startup conditions.

Crystals Selection Notes

Select this component when a 32 MHz base-harmonic crystal is required with low ESR for efficient drive levels. The 8pF load capacitance must match the oscillator circuit's total stray capacitance. Consider the 4-SMD size constraint for PCB layout. Verify that the ±10ppm tolerance meets the system's timing accuracy needs within the specified -40°C to +85°C operating range.

Crystals Part Context

This part belongs to the CTS 402W series of surface-mount crystals. The series offers various frequencies and packages optimized for consumer and industrial electronics. The 402WF variant specifically denotes the 4-SMD no-lead configuration, providing a compact solution for modern PCB designs requiring reliable timing references.

Crystals Replacement Considerations

Direct substitutes include 402WF32012IKR and 402WF32012IVR from CTS-Frequency Controls. These alternatives share identical electrical parameters and package dimensions. Verify pin compatibility and solderability specifications before substitution.
