CM315D32768DZCT

Crystals Overview

The CM315D32768DZCT is a surface-mount tuning fork crystal manufactured by Citizen Finedevice Co Ltd. It operates at a fundamental frequency of 32.768 kHz with a load capacitance of 9 pF and a frequency tolerance of ±20 ppm. The component features an equivalent series resistance (ESR) of 70 kOhms and utilizes a 2-SMD, no-lead package measuring 3.20mm x 1.50mm x 0.90mm. Designed for base mode operation, it supports a working temperature range of -40°C to 85°C and complies with RoHS3 standards.

Crystals Feature Summary

• Surface-mount tuning fork crystal design optimized for low-power applications
• High stability fundamental resonance at 32.768 kHz
• Compliant with RoHS3 environmental regulations

Crystals Applications

• Real-time clock circuits in consumer electronics
• Timekeeping modules in portable devices
• Backup power sources for microcontroller systems

Crystals Procurement Notes

Verify the specific suffix DZCT against official datasheets to confirm the 9pF load capacitance and ±20ppm tolerance, as these parameters distinguish this variant from other CM315D series components. Ensure compatibility with the target circuit's oscillator configuration before procurement.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is required with moderate accuracy. The 9pF load capacitance must match the oscillator circuit requirements. Consider the ±20ppm tolerance for general timekeeping rather than high-precision synchronization needs.

Crystals Part Context

This part belongs to the CM315D series of thin-film tuning fork crystals. The series is characterized by small footprint dimensions suitable for space-constrained PCB layouts. The CM315D32768DZCT specifically denotes the 9pF load capacitance variant within this family.

Crystals Replacement Considerations

Direct substitutes include CM315D32768HZFT (12.5pF, ±5ppm) and CM315D32768DZBT (6pF, ±20ppm). Verify load capacitance compatibility when substituting.
