Crystals Procurement Notes

Verify the specific package dimensions and lead configuration against the mechanical drawing prior to PCB layout finalization. Confirm that the target application circuit provides the required 12 pF load capacitance to ensure accurate frequency performance. Check for RoHS3 compliance requirements if applicable to the end product regulations. Ensure the operating temperature range meets the environmental conditions of the intended deployment scenario.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with ±30 ppm stability is required for space-constrained designs. The 4-SMD form factor is ideal for high-density boards where traditional through-hole crystals are impractical. Consider the 100 Ohm ESR value when designing the oscillator circuit to ensure proper startup and sustained oscillation. Evaluate the thermal performance if the device will be subjected to extreme ambient temperatures within the specified range.

Crystals Part Context

This part belongs to the 402 Series of surface-mount crystals from CTS-Frequency Controls. The series is designed for general-purpose timing applications requiring reliable performance in compact electronic assemblies. It serves as a standard frequency reference component for various consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 12 pF load capacitance, 4-SMD package size, and ±30 ppm stability. Verify that alternative components support the same -40°C to 85°C operating range and similar ESR characteristics to maintain circuit compatibility.
