• Utilizes a leadless surface-mount package design for space-constrained PCB layouts
• Engineered with specific load capacitance and high ESR characteristics for reliable operation

Crystals Applications

• Real-time clock modules in consumer electronics
• Timekeeping functions in portable devices
• Microcontroller system clocks

Crystals Procurement Notes

Verify the exact suffix LLK against official manufacturer documentation to confirm the ±20 ppm stability rating and 7 pF load capacitance specifications. Ensure compatibility with the target circuit's load requirements before procurement. Cross-reference the part number with the latest datasheet from Suzhou Hangjing Elec&Tech Co., Ltd. to confirm package dimensions and material composition. Request sample units for initial validation if available.

Crystals Selection Notes

Select this component when a 32.768 kHz reference signal is required for low-power timing applications. The ±20 ppm tolerance suits general-purpose real-time clocks where extreme precision is not critical. Verify that the 70 kOhm ESR aligns with the oscillator circuit's drive level limitations. The 2-SMD no-lead form factor is suitable for automated pick-and-place manufacturing processes.

Crystals Part Context

This crystal belongs to the 3131M series from Suzhou Hangjing Elec&Tech Co., Ltd., which focuses on quartz frequency control components. The company specializes in R&D and production of crystals, oscillators, and filters for automotive, medical, and communication sectors.
