Procurement Notes

Verify the specific suffix MAHE against the manufacturer's official datasheet to confirm exact electrical parameters and packaging specifications. Ensure that the required load capacitance and ESR values align with the target circuit design before procurement. Cross-reference the part number with authorized distributors to obtain current availability and lead times, as inventory levels may vary.

Selection Notes

Select this component when a 12 MHz fundamental frequency with ±30 ppm stability is required in a small form factor. The 100 Ohm ESR and 12 pF load capacitance must match the oscillator circuit requirements. Consider the 4-SMD no-lead package for space-constrained designs requiring surface-mount technology integration.

Part Context
