CM250C32000DZFT

Crystals Overview

The CM250C32000DZFT is a tuning fork crystal manufactured by Citizen Finedevice Co Ltd. It operates at a nominal frequency of 32.000 kHz with a load capacitance of 12.5 pF and a frequency tolerance of ±20 ppm. The component features an equivalent series resistance (ESR) of 50 kOhms and utilizes a 4-SOJ surface-mount package with a 5.50 mm pitch. Physical dimensions are 8.00 mm in length, 3.80 mm in width, and 1.60 mm in height.

Crystals Feature Summary

• Tuning fork crystal configuration for low-power timing applications
• Surface-mount 4-SOJ package design for automated assembly
• High stability operation within specified temperature ranges

Crystals Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system timing references
• Portable device power management systems

Crystals Procurement Notes

Verify the specific package variant against the datasheet to ensure compatibility with PCB footprint requirements. Confirm that the 4-SOJ form factor matches the target assembly process. Check RoHS compliance documentation for regulatory adherence in the destination market. Ensure storage conditions maintain component integrity prior to soldering.

Crystals Selection Notes

Select this component when a 32 kHz reference is required in a compact SOJ package. The 12.5 pF load capacitance must match the oscillator circuit design. Consider the 50 kOhm ESR value for drive level limitations. Evaluate the physical size constraints against available board space for the 8.00 x 3.80 mm outline.

Crystals Part Context

This part belongs to the CM250C series of tuning fork crystals from Citizen Finedevice. The series provides standard 32 kHz frequencies for timekeeping functions. The CM250C designation indicates a specific surface-mount package style distinct from other series like CM415 or CM1610H. It serves as a fundamental timing element for digital logic synchronization.
