Crystals Procurement Notes

Verify the specific load capacitance requirement against your circuit design, as this unit specifies 6 pF which differs from common 12.5 pF variants. Confirm the ESR specification aligns with your microcontroller's oscillator drive strength to ensure reliable startup. Check current availability status through authorized distributors, as supply levels may fluctuate. Ensure packaging format matches your production line equipment requirements.

Crystals Selection Notes

Select this component when a compact surface-mount solution is required for 32.768 kHz timing. The 6 pF load capacitance necessitates careful external capacitor selection to achieve target frequency accuracy. Consider the 70 kOhm ESR limit when designing for high-impedance oscillator inputs. This part suits applications where moderate frequency stability meets strict size constraints.

Crystals Part Context

This model belongs to the TXC 9H series of tuning fork crystals. These components are engineered specifically for battery-backed memory and real-time clock functions. The series emphasizes reliability in portable devices where power consumption and physical footprint are critical design parameters.

Crystals Replacement Considerations

Substitutes must match the 32.768 kHz frequency, 6 pF load capacitance, and SMD form factor. Verify that alternative parts maintain comparable ESR limits to prevent oscillation failures. Cross-reference pinout compatibility if mechanical constraints differ between manufacturers.
