• Surface mount J-Lead package design for automated assembly
• High frequency stability with ±20ppm tolerance
• Integrated 7pF load capacitance specification

Crystals Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system timing references
• Portable battery-powered devices
• Smart home automation modules

Crystals Procurement Notes

Verify the specific load capacitance requirement of 7pF against the target oscillator circuit design to ensure accurate frequency generation. Confirm that the 50 kOhm ESR value aligns with the driving level constraints of the host microcontroller or RTC chip. Ensure the PCB footprint matches the 4-SMD J-Lead package dimensions to prevent soldering defects during surface mount processing.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is required for timekeeping functions. The ±20ppm stability suits general-purpose applications where high-precision chronometry is not critical. Consider the 7pF load capacitance compatibility with existing oscillator designs. The SMD format facilitates integration into space-constrained printed circuit boards compared to through-hole alternatives.

Crystals Part Context

This part belongs to the 3608S series of tuning fork crystals produced by Suzhou Hangjing Elec&Tech Co.,Ltd. Founded in 2014, the manufacturer specializes in quartz frequency control components including crystals, oscillators, and filters. This specific model represents their standard surface-mount offering for low-frequency timing applications within the piezoelectric crystal industry.

Crystals Replacement Considerations

The 3608S-32.768DT06LLK serves as a verified alternative within the same product line. This substitute maintains identical frequency and package specifications but differs in load capacitance, requiring 6pF instead of 7pF. Circuit redesign may be necessary if the oscillator network cannot accommodate the capacitance change.
